Getting your games from Epic and GoG to work on it takes a bit of work but overall not complicated.
Also if you use an external controller, sometimes it will show the wrong platform glyphs. Personally I just deal with it while using a PS controller but you can just have it show generic ones if you prefer that.
I don’t think the current quick ID/age verification systems can be implemented in any sort of privacy respecting fashion, in part because all these verification services so far, at least as far as I dug which isn’t very far, appear be to some random third parties with dubious implementations that can be bypassed with random images or 3D models in game.
Can it be done down the road? Theoretically… maybe. We already have some online services that communicate with your bank or government account to verify your identity. What I’m guessing is the main hurdle in all of this is implementation time. It takes a lot of time to set up these sort of systems with these constraints in mind and then secure them to the best of whoever’s ability. Meanwhile policy goes like “look how fast they did the thing, we can slap something together in a month” and then it goes to the lowest bidder that can demonstrate any sort of surface level of competence. Which… often times none of the actual professionals who have any shred of an idea would guarantee.
As for the platforms… it’s always a good mindset to be ready to go if you need to and have things prepared (same applies for your workplace btw) but how it will impact instances that are outside of these jurisdictions, remains to be seen.
