"Steam Deck" is clearly not "Desktop Linux", just like Android isn't, or PlayStation isn't "Desktop FreeBSD". It's reasonable to make these distinctions. No one was talking about "operating system kernels".

If KDE isn't Desktop Linux, I don't know what is.
It's not "vanilla", but so isn't Ubuntu, Linux Mint, Fedora Sericea, or whatever else. The underlying stack is the same, there's just customizations on top.

You can run all sorts of things on all sorts of things, but the Steam Deck clearly isn't a desktop machine, and isn't intended or widely used for desktop type stuff. This seems so obvious I don't even know how to explain it. "Yes, but technically ..." isn't meaningful.

My TV runs WebOS. So I'm a WebOS user? Nobody will care that it can run in desktop mode, until people start using that as their daily driver. Spoiler: That's not a thing that will happen.
