No idea. Sadly, like a readied action to move away from a caster who teleports, it will never come up in actual play.That does honestly sound like fun. What would the trigger be for said readied blocking action, though?

Assuming the enemy is teleporting, they have already reappeared before you even start to move. You just can't move faster than a teleport. I mean, you can rule that it works like that but... not happening at our table."If the enemy disappears, I want to move to this space." You'd have to guess where they would go.
I love this visual... and the audio now too!Which is improbable, but no worse than what I've seen players do when someone becomes invisible and hidden- they run around the room like turkeys until they have entered every available space in order to try and find the person.
It actually does say if they are the exception and not the rule. DMG page 252.It's a valid interpretation, but it would have been trivial for WotC to say "oh btw, instantaneous effects cannot be reacted to unless otherwise stated". Instead, they printed things like Shield and Counterspell, which do interact with instantaneous effects, and never bothered to say if they are the exception or the rule.

"For example, the opportunity attack and the shield spell are clear about the fact that they can interrupt their triggers. If a reaction has no timing specified, or the timing is unclear, the reaction occurs after its trigger finishes, as in the Ready action."
So Shield specifically states that it can interrupt its trigger(instantaneous things like damage and magic missile), but ready does not. Some folks want to treat what is clearly not allowed to interrupt the trigger before it completes and treat the ready action like the Shield spell.
You said, "since the spell explicitly inserts a boom in the sequence."
That's not what the spell says. It says you teleport. Then in the space you left, there is a boom.
Suggesting that the boom is inserted between the disappearance and reappearance is not explicit. The only mention of reappearance is in the explanation of what the caster can take with them and then only in regard to the fellow traveler not the caster (disappear and reappear separated not by sequence but by topic).
I'm not sure why you have the idea that I don't know the difference between the words teleport, disappear, and reappear.
Nevertheless, they don't have to have the same meaning in order to happen at the same time; disappear and reappear are understood to be parts of teleport.
That is not a definition on its own. That's like saying the definition of cowardly is acting like a coward.
In then PHB under spell duration, it says "A spell's duration is the length of time the spell persists. A duration can be expressed in rounds, minutes, hours, or even years." It lists measurable time mechanics of the game. Then it goes on to explain that "Many spells are instantaneous...exists only for an instant." This is an explanation of when something happens that isn't "rounds, minutes, hours, or even years." Those spells happen in an instant, happen instantaneously, instantly, immediately.
The rules make a clarification for this 0-time by adding a section about Instantaneous under Duration.
There is no need to have a section on the others individually, but Instantaneous is different. Instantaneous is the word the rules use when the length of time is zero, when duration is not mechanically measurable.
If the game meant for rounds to be broken up into smaller units, it would have done so and created terms for this. Instead -- to simplify things, it decided to use Instantaneous as the smallest unit, effectively 0; if an instant could be broken into parts, the game would have given us other terms for those.
Zero is indivisible
, has no parts, cannot be interrupted; geometrically it is a point that cannot be bisected.
In the real world, people use" immediately" to mean as fast as possible.
But this is a game of magic where the meaning of immediately/instantaneously doesn't have to be distorted.
What happens when you divide 1 round or an action or even a bonus action into parts (whenever you divide a number in the game, round down if you end up with a fraction, even if the fraction is one-half or greater)?
Why would the quote not mentioning the Teleport spell (that does use teleportation effects) make me wrong?
The response I quoted from the compendium was in regard to Misty Step. The compendium's answer then lumped Misty Step and other spells (this quote is from the Spells section) with teleportation effects into a group to explain that spell descriptions are not meant to repeat themselves needlessly.
ETA: Being able to Counterspell a spell with an instantaneous duration has no bearing on the conversation in this thread. The caster can Counterspell any spell of any duration if they see it being cast within 60' of them. Full stop. There is no "Instantaneous" casting time.
