@Strypey A few more details:

* FEP-ef61: Portable Objects

https://codeberg.org/fediverse/fep/src/branch/main/fep/ef61/fep-ef61.md
Invented in, I think, 2023 by @silverpill for Mitra (based on ActivityPub). Currently implemented there and in @Mike Macgirvin ?️'s streams repository and Forte. Part of the plan to introduce almost Nomad-level, but cross-project nomadic identity to ActivityPub.

* FEP-61cf: The OpenWebAuth Protocol

https://codeberg.org/fediverse/fep/src/branch/main/fep/61cf/fep-61cf.md
Invented in 2018 by Mike Macgirvin for Zap (Zot6 development platform; discontinued 2022). Backported to Hubzilla in 2020. Full server-side and client-side implementation only in Hubzilla (based on Zot6, also supports ActivityPub etc.), (streams) (based on Nomad, also supports Zot6 and ActivityPub) and Forte (based on ActivityPub). Friendica has a client-side implementation. Mastodon has a client-side implementation pull request that has to be merged eventually.
