since the method of stacking hasn't been determined yet, you can't say
this.

it would be possible for MultiAdmin to grant additional access, that
SELinux then denies for it's own reasons.

if the SELinux policy is written so that it ignores capabilities, and
instead just looks at uid0 then that policy is broken in a stacked
environment, but it's the polciy that's broken, not the stacking.

yes, there will be interactions that don't make sense, but just becouse
something can be used wrong doesn't mean that there aren't other cases
where it can be used properly.
