I am a bit surprised. I'd consider the ability to do DAC and MAC
concurrently to be absolutely essential, for several reasons:
1. DAC is managed by users, MAC by administrators.
2. They address different but concurrent use cases.
3. Transitioning to MAC will be a lot easier if it doesn't require you
to drop the DAC configuration all at once.
4. You don't propose to drop table ACLs if you enable SELinux, do you?
Same issue.
5. It's possible!

Trusted Solaris was a separate fork of Solaris, which is now legacy.
The current thing is Solaris Trusted Extensions (TX), which is
integrated in normal Solaris. So when the FMAC project produces
something, it should conceivably be available in parallel to the current
TX stuff.
