Actually, there is - the tcpdump man pages (and actually all of their
documentation!) lives in github - the version that this document references
is:
https://raw.githubusercontent.com/the-tcpdump-group/tcpdump-htdocs/7785b0d834e1f77a1d2ec56c96f51f4bf3bf3de2/manpages/pcap-filter.7.txt

Paul Hoffman (CCed) noted that we've discussed this before, and has
(kindly!) offered to write an ID discussing the issue, and proposing the
above - this would give us some process to follow.

So, I'm proposing that, in this case, the authors update the reference to
point at the GitHub link, and we discuss the larger issue when Paul
provides a draft.
Does that work for:
a: the RFC Ed
b: the authors
and,
c: Alexey, who is holding a DISCUSS.
?

I don't think the execution is relevant when it was obviously a bad idea in
the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair of
pants.
