Thank you for the review, Roman.

I've already updated the GitHub copy in response to Mirja's review to
drop the request for the RFC Editor to remove the section.

I had also removed this reference from Section 3.  It was important
background material when I first introduced the draft, before the
technique became more widely available, but I agree that Akamai
specifically need ongoing highlighting there.

This was my own personal research on DITL data, not published as a
special report.  How should I cite?

Yes, in dnsop (mostly at the mic, as I recall).  It used to say dnsop
specifically (version -05) but a couple of people had stronger
feelings than I that the language there should use the more expansive
IETF umbrella.  Me personally, my only strong feeling on the matter is
that, though someone else has suggested that it just be excluded
entirely, I want to see it included as historically relevant because
we did spend time on the EDNS option issue only to have it ultimately
be decided that it wasn't wanted.
