With things as they stand today, this flow is not conducive to Enterprise Identity Providers.

It's not marked optional either, which was the original motivation for taking the safe route and assuming false if it wasn't provided. This would be a feature for us to detect the presence of the claim and act differently if it isn't there. Do any other providers do this? Almost all that I've worked with do support this claim.
Hi , Enterprise providers like ADFS , Okta don't support this as part of the user schema. There is the concept of whether a use is active/enabled which is not the same as email verified always.

If a user is not active, a token should not be minted in the first place. I am trying to understand what additional security does email_verified provided in the context of entire identity providers where there is no self self service use creation. Thanks, Sree
Okta supports , but it looks like ADFS doesn't: We don't know when the provider is self-service or not. Not assuming makes the client logic uniform and less error prone instead of trying to reason about the intent of the provider. There's some discussion when we enabled this validation, including some UAA notes. , specifically
More than 80% of the enterprise customers of Cloud Foundry are using either AD/ADFS . This becomes a breaking change. UAA can add a email_verified claim. However its going to be of little value if the underlying AD doesn't propagate that. My two cents is this check doesn't make sense in an enterprise set up
