Thanks, it’s good to know of other workarounds but I’ll probably stick to RSSHub since I find it easier use/manage. I believe RSS Bridge has a route too.

I wish GitHub also supported rss feeds for issue and pull request discussions, it recently got added to Forgejo.

You should open an issue for this if it doesn’t exist yet, or, if possible, attempt a pull request. The maintainers are kind, welcoming and helpful from my experience.
