Almost definitely this will not happen.
What is against OpenID support for pump?
@engelnyst Mostly because I'm doing things just one way with pump.io -- just one authentication mechanism, just one feed format, etc.
@evanp Will pump.io be extensible (if it's not already) so others can add OpenID support on their own?
Actually, the OAuth mechanism we use is probably close to compatible with OpenID Connect.
So I could see supporting that in the future.
