Fine by me. Maybe something like the below.
Another thing might be to intermix the F and X entries so that
exclusions are more obviously against the F: entries.
There aren't many MAINTAINERS lines changed when the modified
parse-maintainers is run, but I think it reads better.
It doesn't seem the last major reordering with parse-maintainers
caused any significant issue for anyone.
I think having Linus run scripts/parse-maintainers.pl just before
every release or every few releases would make this issue go away.
