 Review comment:
   this feels weird to me; if I have the following
   what happens?  It looks like the drop will be skipped in favor of pass.  Don't see a test
for this since each test calls `filters.reset();` before adding the second filter.
   The pass/drop stuff already exists so nothing for this PR, but I feel that `pass()` should
be removed (should file jira for this)
