Is it possible for someone to review this PR? I am using this in our code and CodeQL which come back neutral are not working.
It would even be better if this is a setting that can be passed along in the with:

[cam-bond]

@dghubble Can you take a look at merging this?

[cmuller-bunnings]

Is it possible to get this PR merged, please?

[juan-vg]

@lazytesting it could also be useful to provide a new input to specify which statuses should be treated as success (default to current if not provided). In this way, neutral could be treated as success (or skipped could be treated as failure) if needed.

@dghubble this topic looks interesting and your attention here would be so much appreciated.
