The problem is currently that authenticators don't respond with the HMAC extension without UP.

In principal we should change that so that it always replies but has different seeds for "uv=1" , uv=0 and up=1, and   uv=0 and up=0.  That probably makes sense for iOT applications as well. 

I personally see this fitting with the WebAuthn flow for SSI and SIOP applications as well as password managers.    I don't think that is mutually exclusive with allowing webCrypto access.   I would like to see both.
