likewise. we should not avoid fragmentation in this particular way. that
is, we can use persistent TCP, or we can avoid sending large messages by
shaping their contents better (smaller signatures, less additional data).
in fact i would prefer to embrace fragmentation and fix it. so, in
addition to my reasoning above, i am also biased against the goal
itself. (i say this not to persuade, but for full disclosure.)
in ~1998, the IETF DNSIND WG persuaded me to remove the MD bit from
EDNS0, and the reasons given then (see the archives) are all still valid
today, especially given that IPv6 made fragmentation worse not better
than it was in V4, and it was pretty broken in V4, the absolute value of
this negative bar was rather high.
