You honestly think the PHB wont be errata/updated with 5.5?
Look, I was right with the Spooky UA, I've been right since. Fizban's is how all races will look, once reprinted.
I didn't know that WotC goons were going to break into your home and forcibly replace your 5.0 books with updated ones. Maybe you need better locks?
It's still optional. All of it is. Even the
edition you choose is optional--there are people who still only play Basic or AD&D, or only 3e or 4e and refuse to update for whatever reason. There is
no requirement for you to change to 5.5. There is no requirement for you to allow Fizan's races when you DM. There's also no rule that says you can't
assign racial ASIs to the races from Fizan's or VGR or VBtWL.
My gods! Did you make this much of a fuss when they decided that all classes should be available to any race? I'm guessing no, since you talk fondly of your
tiefling paladin instead of complaining that it made things more the same when nonhumans could be paladins.
Stop acting like you're being persecuted when all it means is that you have to make a choice: a choice about your ASI, a choice about what books you'll allow at your table when you DM, a choice about what edition you'll play, a choice about what
game you'll play.
(Or maybe, just maybe, you'll find that you'll
like being able to assign your ASIs in the exact same way that you liked your tiefling paladin.)
