Easy thing to say when you're not the one donating your time for free.

I love what Valve is doing for Linux, but longer term, the onus is on them to solve the 32-bit compatibility layer issue (a-la Proton for win-to-linux, as well as their upcoming x86-to-ARM layer).

Expecting all distros (who again, are staffed mostly by volunteers) to do this work separately (i.e. duplicating all that work), for all time, is a big ask.
