Why does it matter who owns them?

Perhaps this was intended to catch user errors?
Actually in the automake I have we don't have this restriction.
We just have a check to make sure the user doesn't `+=' an
internally-defined variable. This check was added because the
implementation didn't allow this to work.
We can and probably should change this. It is a bad idea for a user
to do this, but ...
