The "Why RSS" doesn't mention why instead of RFC4287 Atom.

Name recognition mostly, but you can just call an Atom feed an RSS feed and no one goes to jail for it, so just use the name that gets the results you care about.

Hi thanks for this comment. I'll look into Atom a bit more for this tool. Heard a lot about it.

It was first and thus more broadly supported?

RSS came out in 1999, Atom in 2005. There's not a meaningful difference in support between the two at this point.
