I agree and disagree. I think it's important to make it very visually clear that it is not really a PR, but rather an advanced style checker. I think they can be very useful for assessing more rote/repetitive standards that are a bit beyond what standard linters/analysis can provide. Things like institutional standards, lessons learned, etc. But if it uses the normal PR pipeline rather than the checker pipeline, it gives the false impression that it is a PR, which is not.
