Since the spec hasn't specifed this minimal set of claims one can argue
that it is something specific to an RP. This is how our current
implementation works as well. Although we could define a set of claim bound
to the 'openid' scope, the service provider could control what it needs
from the claims bound to openid scope by using requested claims
Changing 'openid' scope to return issuer and sub claims only will be a
breaking change for many existing providers who rely on the additional
claims (some of them could be mandatory in PoV of the RP)
IMO, if the spec doesn't mandate what should be returned for openid scope
then we can keep our existing implementation as it is.
