If I understand correctly, only public toots appear in a Mastodon user's RSS feed ( @feditips also seems to confirm this notion in this toot: https://mstdn.social/@feditips/108357998963885456 ), which is the correct choice in my belief.
For some reason there is absolutely no documentation of how it works in the official docs site
Also it seems Mastodon also supported .atom feeds in the past but not anymore? as I said, no docs, so idrk.
