My concerns are for both timeline and for wording which makes it
obligatory. I think we should not have stale maintainers in MAINTAINERS
file, thus if someone repeatedly does not match criteria, should be
dropped and moved to CREDITS. However I felt here your wording quite
strong, thus I would assume we will start dropping a lot, a lot of
driver maintainers. I am not sure if we really want it, because from
time to time, such maintainer might be actually active and helpful.

Sounds good. Thank you.

OK, I understand. That's the good point.

Thanks.

Yes, sounds better.

Yep, I understand and I was cleaning such entries as well... :)
