Microsoft Entra Suite: Onboarding with Verified ID

Hi!  Really excited about the possibilities in streamlining identity management.  Couple of questions:

1) Who from US Government is sponsoring / working on this technology?  Is there NIST and / or NARA participation?
2) CMMC is a major government requirement for all businesses working within the aerospace and defense ecosystem (something like 100,000 companies).  Do you have any thoughts on how we can use this to protect and verify identities across clouds? (Azure Gov, Azure Commercial), and how we might be able to use this to enable cross collaboration in M365 (from commercial and GCC - to GCC-H and DOD clouds?)
3) Can you speak to the following scenarios:
Say I work in government, and I want to collaborate with industry - I am invited into industry's application ERP, Digital Engineering, and Teams environments to collaborate.  Today, we do this with external identities, or we have to have a third party shim like Exostar or OKTA that gives me a new identity in order to access those tools with SSO.  How might that change?

How might we use this Verifiable identities to work in a DMZ of sorts - where we can collaborate on specific data types?  Can this enable ABAC?  For example, if I were to tag my data using Purview with certain Need-to-know categories, and I request another person to collaborate with me - who would be responsible for issuing them a credential with the appropriate NTK categories tagged to their credential so they could collaborate on a file?  Would that be at the application level?

Many thanks!
