The thing is - the "swift action" is kind of a bad example of this because it's not just randomly interspersed throughout different books. It's republished in every single freaking book they've made that has an ability requiring a "swift action" - that entire block of text repeated every single time a designer wants to include a swift action ability in a book. Taking up space for those of us who already know what it is, but erring on the side of "not everyone will have every book".

Now I know why I have no idea where I first saw swift actions at.

I'm all for creating a framework that will allow updates to the game rules - if everyone knows that there's a rules upgrade that came out with the PHB II and you can either get that book or get the erratta online that's great. But I also think that tables need to re-assess their definition of "optional". At our table, every rule is potentially optional. We're not afraid to say yes to things, but we're also not afraid to say "not at our table". And that goes for rules in the PHB I itself - if we find a rule, a spell, a feat or whatever that interferes with our game we throw it away. "Core" should not be a synonym for "required" - just about everything in any of the rule books is a "suggestion" at best. No table should feel like it's being forced to implement something they don't like just because WotC put it in a book.
See I would have a problem, depending on how much space it takes, if the eratta and updates are put in a PHB2 I'm buying for other things and are also offered for free. I'm essentially paying for free material, and missing out on more material for the new stuff that's introduced...which leads to me buying another book for that other material.
I don't think the problem is that people feel somehow shackled by what is established as core, I know I don't. The thing is if I'm only using the PHB, DMG and MM as my basis for the game(regardless of what I change within those books) saying a core book only game means everyone knows I'm only using the rules presented in those three books with any modifications I choose to make. Why? because the covers of the 3.5 PHB, DMG and MM all have core rulebook across their cover. Contrary to what's been stated, no other books(including PHB2 or DMG2) have this designation upon their cover in 3.5

I prefer a single PHBx, DMGx, and MMx each year that groups things a bit more broadly to the current glut of "complete X", environment, etc. books.
As far as the term "core" goes, I agree that I've always consider that to mean the baseline entry products. I don't have a better term for non-setting stuff, though.
Since everything will now have numbers on it, I'd suggest the term "generation" for each increment of "core" books. If you want what would currently be "core-only", it's "first generation only". "Eberron + core" is "Eberron + first generation".
I don't know if I agree with the broad groupings, since it suggest one of two things...
1. Minimal space so you're back to splat-books or to be continued in PHBX type model to fill out each class or maybe power group anyway. ( this is why I feel the number of splat books will not decrease. With this model you're continuously introducing new character types that will need support, and I don't see a yearly PHB being able to do this for every character type, the number of which are being steadily increased, previously presented while also introducing new ones that need their own support.)
2. You can no longer buy what you specifically want for your character or game. Instead you end up paying for alot of things that you don't want or won't use.
I would be fine with a "core rulebooks" and "official expansion" designation. But then again this probably won't sell as well as making everything core so consumers feel like it must be purchased for a complete "core" game.
