Ask HN: Is GitHub Sherlocking Actions?

GitHub recently announced an auto merge PR feature (looks great!). However, I've been using an OSS GitHub Action for a while (link below) and I wonder if anyone has noticed other OSS Actions being quietly ported into GitHub (one that comes to mind is the stale branch feature introduced a while back). I have published Actions - and would like to publish more - but I'm a little concerned by this. Should I be?
