That’s… mostly because of popularity and it depends on whether some service is offering OAuth and if the website in question is using THAT identity provider.
For example, mastodon is technically offering it.
github.com/mastodon/mastodon/pull/16221
but this is the docs page:
docs.joinmastodon.org/admin/optional/sso/
So the answer in this case is to just grow, promote and support what we’re already doing: fediverse stuff.

There’s really no reason something like that couldn’t exist. A foundation would just have to decide to dedicate the resources to it.
The issue is it would have to gain significant adoption in order for web admins to think to include it. This list here is actually a lot larger than you usually see. It’s often just the big 2 or 3.
