I’m with you on most of your priority list, but would swap perpetual digital with physical.
I would also point out that physical need to be fully on disc, otherwise they’re at best as good as game key cards (doesitplay.org is very useful there).

I think PC gaming is unfortunately the only “sustainable” option nowadays to allow for both native games and emulation to run today or in a decade. With how console manufacturers, especially Microsoft, have been aggressively pushing digital, there’s little hope of having any physical backcompat in consoles moving forward.
