If that is the case, I'd rather we introduced data that has actual
meaning, like something similar to "connector" (even though connector is
the wrong thing here since an "xdg_output" might not have one, maybe,
something that doesn't identify the monitor itself, but how it is
connected, if that is what you want) and then a different thing that is
more meaningful to a user interface. Then whether the "this is string is
user interface facing" should have anything to do with where the wire is
plugged in or what is actually plugged in can be up to the software that
is responsible for generating that string, but it should be clear what
its purpose is.

If we'd add quotation marks, spaces etc I'm sure many things would break
here and there. If we start adding such restrictions, it'd hardly be
suitable as a "human readable" kind of thing.
