Any reason to keep this around in 2.x ? What we have AFAIK is a now defunct standard V2 and open id connect is to much for core inclusion (IMO)
Providing there are hooks and a mod can be created without core edits; I don't see any harm in removing it.
+1
I mean, who even uses OpenID any more - other than LiveJournal and I think they even use the old support that SMF had rather than OpenID v2?
Its now been removed in the latest PR to 2.0
