I was claiming that the Low-Water-Mark-style implementation of a
taint-oriented strategy is more compatible with traditional UNIX than
a demotion-free Biba-Strict-style implementation would be.  I wasn't
making any comparison with your current SELinux policy other than to
say that the least-privilege strategy it uses is different from the
taint-oriented strategy Low Water-Mark schemes use.

I'm not trying to talk you out of your preference for the
least-privilege strategy.  I'm just pointing out that SLIM seems to
implement one of the few protection schemes not already covered by
SELinux.  Consequently, if you'd like to demonstrate the generality of
the FLASK architecture or the LSM interface, I think SLIM deserves
consideration.
