Not really for tree wide mechanical changes. It is much more preferrable
IMHO to only CC people who should review the intention of the change
rather than each and every maintainer whose code is going to be changed.
This is a case by case thing of course but as soon as you see a giant CC
list from get_maintainer.pl then you should try to think twice to use
it. If not sure, just ask on the mailing list.
