I see your point, but as I mentioned this was as per suggestions from
other maintainers only :)
Perhaps a good topic for the next LPC maintainers meetup - i.e. would
maintainers be more happy with subpatches for their specific area v/s
being cc'ed on a single patchset which touches other areas as well
(but are required for enabling a feature in its entirety).
