This probably isn't the right venue for this discussion.
I'm going to go with Mark's answer: "nameservers that don't set TC
[truncated bit] when they can't fit glue are broken RFC 1034." When
that happens to be both TLD servers for a particular TLD (.gov), I'm
calling that an operational issue.
I have a workaround. I'm happy. But the folks running gov-servers.net
*really* ought to have a discussion with their vendor.
I'm pleased to report that the fix for this problem was finally deployed,
as of yesterday. You should now find TC=1 in responses from the .gov name
servers when the glue won't fit:
$ dig +dnssec +bufsize=512 @a.gov-servers.net www.nsf.gov a
;; Truncated, retrying in TCP mode.
