Having DPK + attestation be an equivilent to a single device credential is a goal.

I think it is an unrealistic short term goal.  We do need to finish the specs so that can be developed, however for the near term we need to prepair RP to deal with multi-device credentials with no attestation.  

We have a lot of positive deployment stories for RP to replace passwords and leverage multi device credentials that are backed up for account recovery.

I understand there is a glass half empty side of the story, but in the short term I would prefer to concentrate on the glass half full and not fixcate on DPK and attestation.   Deploy the use cases that don’t require that.  

For the ones that do there iare still non discoverable credentials on Android, Discoverable credentials on Windos, and security keys.  Not the end of the world.
