You've convinced me.  I think the first is a redherring as no one uses the tags, but the second is a good argument.

That said, I think the second argues that -P generating category= is the
wrong approach.  Instead a new flag should just let you add arbitrary
stuff to the mtree file (subject to validation that it is well formed).
