Thanks Peter, this was actually helpful and enchanced my mental model.
I think I get get away for now with a user's tree rooted in the system
tree. My graphics environment (sway) can start necessary services
when it is started.

By testing I meant checking if the directory has an active process
watching it. I believe there is a function in skalibs fd_lock [1]
that svscan uses to check if another svscan runs there. I think it is
just a matter of exposing that function as standalone executable.
