Indeed so.

That would be ok with me, but it might be hard for the Debian/Hurd guys.

There is never any question of ABI breakage that I know of, just that it
works or it doesn't or it has too many PLT entries and is less optimal.  
It seems to me the simplest thing for now would be to make it easy to just
disable all the hidden_proto stuff entirely and have Hurd do that.  
I'll add something.
