This is a worthy goal, but I see it as a goal separate from what the
patch is trying to achieve. From what Paul is saying, the change you
are objecting to introduces a check that is correct within the current
implementation, and makes the kind of assumption that's already used
everywhere. Why can't we use the current framework as is until the
cleanup is done (BTW: who's going to do it, and when?). Admitedly, we
have to document a temporary assumption, but I don't think this will
affect the symbol interface cleanup you're suggesting all that much.
