I'm surprised your comment is showing up grey (downvoted). It' a perfectly reasonable solution. I'm considering adding a new "remote" plugin type to our server for running hooks in sidecar processes. It wouldn't be my first or second choice but it makes lots of sense if you have to talk to something that might have bad p99 response times.

Please feel free to reach out to me (info in profile) if you ever want to have a chat or are looking for some fun work.
