For clarity, I'll try to restate my suggestion more succinctly:
... an IPSRA proposal which uses a legacy credential,
and which also incorporates a mechanism that replaces the
legacy authentication transport mechanism to provide stronger
authentication based on the credential.
Do you still believe this is "distinctly out of scope"?
If so, please elaborate. This point is not at all apparent from the requirements
spec, and I know I'm not the only one to interpret it in a broader way.
There is clearly an intentional bias for mechanisms that keep legacy
authentication services and transport mechanisms intact. But the current
draft does not (and I believe cannot) make this an *exclusive* requirement.
I find it difficult to see how one can exclude supporting a certain class of
authentication mechanisms, "legacy" or not, without making an explicit list
of what can *only* be supported. Doing so would seem to risk making any
IPSRA proposal artificially narrow, or immediately obsolete.
For another view of my concerns, see my follow-up to Hugo Krawczyk's
comments, where he raised some good points.
