Custom message during authentication

[magnushoflin]

Agree, it's a good feature and it would be nice to have it supported it in the technical framework. The only drawback I see is that you, as an RP, might not know which IdPs that support it, making it somewhat tricky to use. But still it's a lot better to have the option there than not. Also, it's very related to signMessage and therefore natural to include.

Yes, but we can solve this by having an entity-category in metadata where an IdP can announce its support of the feature.
