It is not at *all* clear how multiple optimizations for a single task should interact. No simple logical operation is right in all cases, and in fact in most imaginable cases the desired behavior turns out to be independent of all but one of the optimizations. For example, given both `seta` and `skip-unless-files-changed` optimizations, if SETA says to skip a test, it is low value and should be skipped regardless of what files have changed. But if SETA says to run a test, then it has likely been skipped in previous pushes, so it should be run regardless of what has changed in this push. This also adds a bit more output about optimization, that may be useful for anyone wondering why a particular job didn't run.
