That is a good question I also thought about… First, I don’t have any more details on this (if you meant me personally at all)… this might be a stretch, but my personal speculation (!) would be that CXP/CXF would maybe not only be used for credential transfer/exchange, but maybe would also result in a new “CXF export format” – and that may be the long-term passkey backup plan. (?!?)
Whether it is that counter issue instead – I have no idea…
