See the thread about Re: call for ideas: tail-heavy IETF process for

because there is a discussion on issue-tracker does not mean the document is

implementers know what and why.

Yes.

I have not followed this discussion, but my cursory read of the tracker
ticket shows the WG blew off the issue by claiming that historical
unsophisticated attacks can be easily thwarted, while completely ignoring
the case where the target domains exist. Aborting an amplification attack on
failures does not do anything about the case where an attacker goes to the
trouble to make sure all the quires will return valid answers. Either the
issue-tracker discussion is inadequate, or this is exactly the kind of thing
that adds excess delay and workload to the IESG review process.

It seems that the above is related to Issue #24 [1]. I posted a rough summary of the initial discussion [2]. I took a look at the IETF 83 minutes and I found "DNS amplification attacks" [3] mentioned. There was a message from Andrew Sullivan [4].

A working group may decide to blow off the issue if it wants. The issue can be listed in the write-up.

S. Moonesamy
