I know it sounds wrong, but couldn't you add the info on all declaration
and let DCE remove it if not needed?

Ie. I'm actually surprised that it doesn't... Does it?

Oh, I remember vaguely having a similar bug on our front end, because you
don't want to create a declaration for both types if they're related and
end up with different metadata for each path. I don't remember how I solved
it, but it was definitely the wrong way, because Dwarf was, by far, the
worst part of our bridge. ;)
