Me too—-BUT now we have create your own package of bonuses. The genie has been let out of the bottle for good and ill.
We are already creating our own packages of bonuses...

In a few years’ time, the pre tasha’s experience won’t even be remembered.
I don't think so. You have a lot of pushback IME on what Tasha's did. For new players, sure, they will never have experienced "pre-Tasha" so they won't know any better (or worse, depending on your POV).
Barbarian halfling? Dwarf wizard? As common as any other. My grog is showing there—-used to enjoy surprising the party with an odd pairing but those days are well past now.
While I think this will be lessened, it won't go away. Many people will come to the game from media, particularly main-stream movies, and while tropes are challenged, they will still exist (Orc Barbarian, Dwarf Fighter, Halfling "Treasure Hunter", etc.).
Darkvision is just something people will choose to have 99% of the time. Limiting it is probably not going to be widely done.
It is a choice DM's have to make and enforce IMO. I've reduced the number of races with darkvision to less than 10-12 IIRC.
Another option I like is what we call
shadowsight, which turns Dim light into Bright light, but doesn't help in Darkness at all. Many races would have
this IMO, but not true Darkvision.
