There should be nothing wrong with a 64 bit program launching a 32 bit program. If anything, it sounds like Valve is using that as some sort of "comparability insurance"; if you can run steam, you can run almost all games on steam.
Bazzite shutting down would be tragic ( for me ). I've been quite happy with it. Slowly convincing people to switch. Bazzite was also a relatively low step compared to fixing them a standard distro as all the stuff they want/need is already readily available.
Telling people I decided to promote another distro because the old one stopped is only going to make me have to restart my efforts with an additional hurdle ( how do you know this one won't stop ).
I tried a few distros. But I didn't like garuda very much, nobara was okay'ish. Bazzite really clicked for some reason, despite needing a bit of getting used to.
I'd hate to go distro hunting again. Or try and update cpu schedulers and not brick the whole system.
Steamos is based on arch and also immutable. Can't they do something like that. Never liked bazzite cause it was fedora based. I feel like any gaming distro should be arch based and making it immutable would fix the arch breaking fear.
Why is everyone downvoting? It's not really a stupid question when they apparently already tried it.
Building a distro is hard. Building a distro on existing architecture like uBlue is easier, but still hard, especially if you want to do it right. I believe uBlue was the right choice. This is just someone over in upstream doing something stupid.
