The thing that concerns me most about CIPSO is that even once users
migrate to a more SELINUX native approach from this CIPSO stuff, the
CIPSO code, it's bloat, and it's maintainence burdon will remain.

It's easy to put stuff it, it's impossible to take stuff out even
once it's largely unused by even it's original target audience.

And that's what I see happening here.

This is why, to be perfectly honest with you, I'd much rather
something like this stay out-of-tree and people are strongly
encouraged to use the more native stuff under Linux.
