It’s not yet enabled by default and existing 32-bit prefixes needs to be recreated
Arch is migrating to it
Native Linux games on Steam run on top of steam-runtime, a collection of libs (32 and 64 bits) running in a container called pressure-vessel. In theory they don’t need 32 bits distro support.
Steam Linux client itself is 32-bits. Unfortunately
Since Wine 9.0, you can run 32-bit windows apps on 64-bits directly, without the need for 32bits distro support. It’s called WoW64.
You can in some cases, but not all.
Wine has two forms of WoW64. Old WoW64 uses 32-bit libraries and has been around for a long time.
New WoW64 (first available in Wine 9.0 if built with a special option) works without 32-bit libraries, but is still incomplete. It cannot yet replace old WoW64 everywhere, and even where it can, it reduces performance in some APIs. (For example, OpenGL.)
It will eventually make sense to drop the old one, but doing so now would be premature.
As I understand Steam wants to be compatible with mainstream. Since they has released a native client for Mac Silicon, I think we may also see a 64-bit native Steam client. At least I hope so :)

Thanks for the info. Things looking promising.
