I don't see why that would matter. If it's applied upstream it will find its
way into -current eventually, and if we decide to patch it ourselves, who's to
say Pat wouldn't be receptive to that, given the right arguments?

I don't really see the point. There's build automation tools out there
already. No reason to reinvent the wheel.

That's unfortunate, but we won't know until someone tries. If it's a change
worth having it's a change worth arguing over.
