I have a few workflows where we evaluate a branch for changed paths and do a circleci step halt if there are no hits. This works well enough, but the issue is that in the UI the job containing step is still marked in green (as is the skipped job). Ideally we would have a halt syntax that allowed recording a success, failure, or new (as far as I can tell) "skipped" state for the jobs that didn't run for a particular invocation (e.g. a PR changeset).
