Ok, this is something I wasn't aware of.  I agree that dummy ebuild
should not be necessary here.  However, I'm also not sure if distfiles-
local is really the proper way either, especially that I don't see such
files on woodpecker right now.

I don't think the matter is urgent right now, so let's ponder on it
a bit.  In particular, I think we should have a clear indication of who
added which files, when, what for and where they came from.  Those are
precisely the things that the current distfiles-local approach misses.

This is also something that needs thinking.  I personally don't mind
having one but it would be nice if it was able to account for geodns
and such.
