I don't see why 'piggyback on what [Steam deck is] doing' wouldn't work just as well on any distro, you'd just have a load of extra stuff you're not using too.
That's nothing against Arch, it's what I use, I'm just saying really the only magic is in doing less.
You might be right in terms of a desktop environment. But Arch does have its own opinions, eg it picks systemd by default. And it gives you a default kernel that has a few patches applied and a config picked for you.

Yes, that was in my original comment. However setting up all the configs take a bit of time, and with Arch you can just literally copy large parts of the config files from the Steam deck.
One advantage that Arch has over many distros: as a rolling distributions it's usually easier to get up-to-date packages, you mostly get them by default.
No, just because the Steamdeck's distro is built on Arch, and so you can piggyback on what they are doing.
