This is bad. Because,
a. Switch 2 can get bricked when Nintendo wants you to upgrade to the “Switch Tree.”
b. If you discover a purely unused switch 2 decades later it will be useless. It’s bricked unless you get that Switch 2 update.
c. It all ties to that Nintendo bricking terms of service terms.
Box64 takes care of the architecture, SteamOS is just well-packaged Arch Linux which has ARM distributions, and people have gotten Steam+games running on the Switch 1 under Ubuntu Switchroot. Nvidia open-ish source drivers exist for Linux and work more or less.
