Perhaps I've interpreted this the wrong way, but I took this to mean
that those security subsystems which don't flow through James should
use the X: entry to exclude themselves.  For example, here is a quick
diff to exclude SELinux:

diff --git a/MAINTAINERS b/MAINTAINERS
index c13b9fb3be0b..dc0b31121459 100644
