Manu, I very much appreciate you diving into this. I have been getting
bitcoin wallet developers interested in taking a look at cross-wallet
standards, and I'm also trying to move the languaging and architectural
approaches to support more than just digital asset wallets but also DID and
credential wallets.

I've written up today some thoughts about requirements for multiple
sequential or animated QR codes, among which are many message encoding
issues: https://github.com/BlockchainCommons/AirgappedSigning/issues/4

I've also repeated my thoughts on a bech32 like encoding approach for URI
and single QR codes in
https://github.com/BlockchainCommons/AirgappedSigning/issues/5

I'm also working on a document to try to puzzle through some other wallet
languaging issues about personas, wallets, purses, accounts, profiles,
master seeds, derived keys, etc. It still has a long way to go to work for
the bitcoin community, the broader blockchain community, much less the DID
ecosystem, but I feel is coming along quite well. If there are folk
interested, I'd be glad to invite you to the HackMD collaborative document
or schedule a Zoom session to walk through it.
