This is probably obvious, but had gmail.com done what yahoo.com
has done, that could I guess have a pretty significant impact on
the IETF getting stuff done for a while since a lot of folks in
the last few years seem to have migrated their IETF mail to
gmail.com as a reasonable way to get around corporate this-and-that
issues.

Maybe people who've done that might want to consider whether its
such a good plan for so many IETF participants to be dependent on
just one service now that we have a demonstration that s/none/reject/
in one TXT RR can have such an impact.
