It isn't an arms race, since the intermediaries want to co-operate with
us, not break our protocols. One would expect that except for incompetence
the problem will get smaller over time.
If they are cooperative, then we do not need to put in features that try to
work around the damage they do to a message.
Standards are long-term mechanisms. If the intermediaries are going to get
better anytime soon, then we do not want to have cruft in the standard that
purports to fix short-term problems.
