I still think there's a strong likelihood that receivers will choose to
use SSP selectively, i.e. to apply it only if their first level
reputation check on an existing signature does not meet their threshold.
In this case, the MUST is still ambiguous... they may have embraced the
standard for certain cases but not for others. The spec seems to imply,
by using MUST in certain cases, that it is an all or nothing
proposition.

This would be a very useful addition.
