[Openid-specs-ab] SIOP and webauthn

[Sam Goto]

I don't recall the timelines precisely, but didn't we develop WebAuthn
before SIOP?

I think i understand why SIOP was developed, if it was done after WebAuthn,
because, IIRC, WebAuthn didn't have the cross platform syncing capabilities
that it has today, but i do wonder where SIOP would fit today.
