For some devices, gaming is all they need to do.

Serviceable isn’t good, even if gaming is all you do, you’re better off with a regular distro — this was brought up already in the comment you’re replying to.

EmuDeck, Heroic and Lutris integrate directly into Steam. With a single click you can add a shortcut in your Steam library

Adding a secondary launcher to a launcher is bad design. Again, this is something that I brought up in the comment you’re replying to, along with having to use hacky software that only exists to remedy SteamOS usability problems, of which emudeck is one.

I’m not sure how they can make it any easier

They don’t have to. The problems I mentioned only exist because of SteamOS dumb decision to completely segregate the “desktop” and “gaming” experiences. They’re fixed by just letting me use my computer. Imagine if Steam logged you out every time you exited Big Picture mode, because this is pretty much how SteamOS currently works. I think you guys are cutting a LOT of slack to SteamOS because of what Valve did for Linux gaming but there’s really not a single reason to use it over something like Bazzite (not the Steam Deck version, obviously).
