1.  Network Time Protocol Extended Information Extension Field
https://datatracker.ietf.org/doc/draft-stenn-ntp-extended-information/

I oppose adoption of this draft; we should not be packing a bunch of
unrelated information into a single EF like this. I do agree on the
need for an EF that provides a UTC-TAI offset but
https://github.com/dfoxfranke/ntp-leap-seconds does this better.

2.  Network Time Protocol I-Do Extension Field
https://datatracker.ietf.org/doc/draft-stenn-ntp-i-do/

I oppose adoption of this draft. It would be much better to define new
NTS-KE record types for exchanging this sort of static information.

3.  Network Time Protocol MAC/Last Extension Fields
https://datatracker.ietf.org/doc/draft-stenn-ntp-mac-last-ef/

I oppose adoption of this draft. Last-EF makes no sense except in
conjunction with Harlan's parsing proposal which is already a dead
document. The multiple MACs and random padding are silly as I already
explained more than three years ago.

4.  Network Time Protocol Suggested REFID Extension Field
https://datatracker.ietf.org/doc/draft-stenn-ntp-suggest-refid/

I oppose adoption of this draft for the same reason as the I-Do draft,
but also because I oppose trying to pack yet more conflicting
semantics into the same 4-octet field.
