My understanding is that they are in a happy place where they are just as usable as SHA-1 based repositories have been. As we have well-worked out interoperability design but no implementation, it may have to change once we discover something missing in the design, though. But without such clarification, you already know the answer to the above question in the message you are responding to. Having a migration path means "possible data-los" is not in the picture.

Good.

THanks.
