I have not seen anything to complain about here, so why would I?  :)

That would be good.  But always remember, no one, not even a maintainer,
is there as a "gatekeeper".  Everyone can be routed around, or
accidentally forgotten to be cc:ed or patches can come in from other
subsystems as needed.

So adding more reviewers is always great, but it's never a "requirement"
that all people have to review everything before things are merged.

Well said, this is a tough area when dealing with both undocumented
hardware combined with a spec that is not public.  Everyone's trying to
do their best so we should always assume that first.
