Just to clarify, are you referring to the current handling of the SteamCMD and Legendary binaries?

If so, thanks for pointing out the XDG standard as the current implementation was mostly to get something quick and dirty going and improving it later, with adhering better to standards + updating them (if they are manually downloaded by Monarch).

Yes.

And distros like Void and Arch already have Legendary and upgrade it with package manager.
