Note that ghcup makes some assumptions about structure of files in XDG_BIN_HOME. So if you have other tools installing e.g. stack/cabal/ghc into it, this will likely clash. In that case consider disabling XDG support.

Which assumptions does it make? What will clash and when? I very much prefer XDG-style installations, but I don't want to find out the downsides the hard way afterwards... ;-)
