With Nostr, for example (or even RSS), you can fully understand it from end to end, in minutes. As a former IPFS deloper myself I can assure you in just 2 days you didn't even understand the CAR format of a repo, unless you had prior experience.
I looked at nostr but lost interest when I noticed there was no provision for key rollover. I guess that’s fine but ephemeral identities. Is there a concept of using a domain name as a handle like bluesky? It’s been a few years so maybe it’s worth a second look.
Key rotation is an unnecessary complexity, imo. I never heard of anyone wanting to use a domain name as identity in Nostr, but there's probably a NIP for that where a domain can prove it owns the private key, and be used as an identity.
I mainly quit Nostr development because it was all essentially controlled by 'fiatjaf', and he was making bad decisions, and a childish intolerable arrogant person in general whenever people asked him to justify those decisions.

The one thing that completely turned me off nostr is the idea that my identity is tied to my private key and that it can not be recovered. I'd guess that the reason you don't hear from people like me is that we simply don't bother to work with such a boneheaded design.
