Huh, that's not my understanding. I was there when it first came out, and the whole point was to allow you to use any URI of your choice as an authenticator. Let's see what the first line of Wikipedia has to say:

OpenID is an open standard and decentralized authentication protocol

Huh. 🤔

You might be confusing the old OpenID with OIDC (short for Open ID Connect), which is based on Oauth2, an entirely different technology.

OpenID was definitely more decentralized compared to how OIDC is commonly used these days, but OIDC has various little know options to do similar things.

See what CIMD solves for. “Innately centralized” was probably a poor choice of words, but OIDC not a good fit for an open social web with decentralized identities and a plethora of small identity providers that cannot be known upfront.

Forgejo has a feature (that people usually disable) where you can bring your own openid connect url and use it to auth. So if I have my own OIDC provider I am self hosting, I can just use that to log in.

Most people only use OIDC for google and microsoft and whatnot but it's very possible. I don't realkly see what FedCM offers that OIDC doesn't or can't, or why we shouldn't be adding features to the existing and popular OIDC instead.
