Integrate with FedCM?
How can we best support a single UI for selecting from either wallet or federated credentials? Eg. for proving age or organization affiliation.
Split off from #10, no longer a v1-blocking concern for Chrome.
The starting point should probably be whether federated credentials and wallet-stored credentials should be in a single UI. I think I understand the motivation to do this from the UI perspective, but, arguably, these two have different security, privacy properties and different trust establishment mechanism (some might even argue a word "credential" has a different meaning in federated and wallet-based models) and should not be in a single UI.
