I think the primary targets/victims/beneficiaries of this process should be
the connectors. To me, it makes much more sense for them to be filtering
their members on ingress, especially since BCP38 does tend to crop up in
various NSF solicitations. If Internet2 does the filtering, it can hide
these downstream issues. It is appropriate for Internet2 to identify
"offending" traffic, but once it has been identified, the connector should be
encouraged/cajoled/shamed to fix the problem.

International peers are another matter. One would hope that they would have
similar policies.
