@dalias yeah, except... I did the second implementation of LID, and a reference implementation of YADIS. When OpenID was happening, I said "just give me one feature: pass me a display name".
By the time all of the rest of the cruft got added, that had disappeared, and in the 99% use case (blog and forum comments) OpenID was less convenient.
Banks were never gonna use it, for the same reasons Passkeys are locked to vendors.
