Re: [OAuth2] Infrastructure for tracking token expiry time

[Zsolt Parragi]

Hello

This API looks simple for providers that use JWT access tokens, but
what about providers that use opaque tokens and an introspection API
to check validity instead? Some validators might not be able to
provide anything meaningful without a periodic call to a "check
validity now" method, and even some providers that use JWT access
tokens support immediate revocation, where these periodic checks would
be useful.
