Given that I have confirmed EDNS works with:
dig edns-v4-ok.isc.org TXT
dig edns-v6-ok.isc.org TXT
and that I don't have a firewall that would/should be dropping
(properly) fragmented UDP[1] and I have no other indications of packet
loss, are we looking at a bug in BIND9 to explain this (mis-)behavior?
Cheers,

[1] I'd be happy to test and provide evidence if anyone has a test that
will do so. Perhaps a dig command targeted at one of the many failures
that my logs are constantly showing?
