They work and are required on < RHEL 6.*

Yes

Not my call to make

However, i noticed today that recently you did a little work in gentoo trying to call all the admin interfaces in sysadm.te

Please make sure that you build test it thoroughly (also test build monolithic, direct_sysadmin etc)

Not because you may want to support monolithic build in gentoo but because you want to make sure you at least stay to some extend compliant with refpolicy

I would be a shame if you spent a lot of time on some feature and much later determine that its not upstreamable becuause upstream 
needs to support functionality that gentoo does not need to support and thereby neglected to test.

I am saying this because i vaguely recall my trying to call all those admin() interfaces in sysadm.te in refpolicy but it failed to pass the build test then.

I might be wrong i am just giving you an heads-up in advance
