My understanding (which could be wrong) is that the general idea is to
deploy a new protocol that is an evolution of the existing one.  DKIM as it
stands today would be unmodified, but would theoretically become
obsolescent in the face of the new thing once it reaches critical mass.

If I've got that right, then it might indeed be good to make it clear in
the charter that this is the express intent, and not extensions or
enhancements of the architecture in situ.
