I totally agree with Brad. The use cases, goals and proposed solutions
are so fundamentally different that I can't even see (at this point in
time) what the two groups could converge on.

It would be great if we could pin down exactly what should be done for
the two groups not to step over each other. From what I understand,
the initial argument was mostly about naming the specification and its
interfaces. I think that at this point it should be no problem for
WebAppSec to rename the Credential Management API to something like
"Password Manager API". The interfaces could use "identity" instead of
