Are atom feeds "fediverse"?

so like, atom feeds were explicitly designed with “refeeding” (roughly the same thing as boosting) in mind, so it’s basically a selfhosted, decentralized equivalent to social media, however they never really got used that way for various reasons. but still, does this mean they are “fediverse” too?

we ask because the secret hidden purpose of fedilinks is ultimately to promote atom feeds, and we’re wondering if it would be appropriate to bring that stuff here.

Many ActivityPub servers generate Atom or RSS feeds. I think all these standards belong to Fediverse protocol family.
