It should be insufficient to get those words into an RFC without
evidence that they are appropriate. RFCs are neither the sole nor
necessarily the appropriate place for that information; they can and
should cite published work that validates their claims. Whether we
should trust the IETF to do that is independent of whether we should
ignore them solely for the benefit of individual performance.
