Indeed, but at least the typical failure case (when the library name
differs from the expected one) is that the plugin isn't loaded and the
program can report it, rather than that the wrong plugin is loaded
silently as occurs with the numerical ID.

As Stefano pointed out, it does in fact say "plugin types should be
identified by file and label".  I admit the text is strange given the
presence of the ID as well.

So make a pseudo URI or something out of it.

Anyway, the situation is a bit unsatisfactory either way and I don't
think we disagree on that -- probably not much point in arguing about
the details these days.  A proper URI is a better option in any
circumstance.
