I guess this depends on one's view of what consitutes "very little collateral damage." I've had my own mail blocked, both when sent from my current ISP, Earthlink, as well as when sent via the servers of my last employer, BMC Software. As mailing list admin for three IETF-hosted mailing lists (disman, agentx, and ltru) I've seen bounces and automatic unsubscribes due to IETF's infrastucture having been blacklisted. Thus I'm rather skeptical about "very little collateral damage." This may be due to misuse of DNSxL technology or other reputation systems, but if this small sample is any indication of the extent to which the technology is being used inappropriately or incorrectly, it suggests that significant educational effort in "correct" or "appropriate" uses of the technology is needed. (Assuming that it's not an indication that there are fundamental architectural flaws...) "Informational" makes sense to me at this time. "Proposed Standard" does not. http://www.ietf.org/mail-archive/web/ietf/current/msg53668.html sums up the issues nicely, in my opinion.
