Thank you for raising these concerns, Daniel. I personally found nothing
in what you wrote with which to disagree... and I tried really hard to
find a nuance that would send us down different paths.

I think what you hope for is reflected in the Encrypted Data Vaults
spec (which we hope to build Identity Hubs on top of), and if it isn't,
it should be... because what you're saying should be at the heart of
what we're doing. Again, personal opinion. I'm almost certain it's the
opinion of Digital Bazaar. It also aligns w/ other cross-community
discussions I've had over the past several months.

The devil is in the details, but I think we're all headed down the same
road... we'll find out if that's true on Friday.

+1, I feel like that's what we're trying to do.

+1, that's a design requirement for Encrypted Data Vaults, on which
Identity Hubs should be able to be built (if we did the design correctly).

I'm being brief because I agree with everything you said, Daniel... just
wanted to make sure you know that there may be more alignment than you
