I don't think that is 100% right. Yes, of course add a general note at
the front stating that the current standard is 8200 but that many
implementations were based on 2460. But then, change all the references
to 8200 and add text where there is an actual difference between the
two cases. So far I think two have been pointed out:
https://mailarchive.ietf.org/arch/msg/opsec/StjbjvCP9PLC3ssnTKYO6jqFgk0
https://mailarchive.ietf.org/arch/msg/opsec/9FigBATRkVHAurXv3aNNR-Z46JU
but there may be others.
