In such cases I think it should be the next-level-up maintainer whose
ack should be chased; at least that's what I typically would do. This
would be George in this cases afaict. Otherwise, if George wouldn't
have the cycles to look at this closely enough to give an ack, I'd be
happy to provide mine as "replacement".
