I don't think anyone has seriously suggested that. It was suggested
that it was okay to make the default sendmail config assume a GENERIC
kernel, which has v6 in it, but even that idea has been abandoned.

No one has broken the latter. All that happened was that there was a
line in a sendmail config that, prior to some hacking done in the last
24 hours, would have had to have been commented out on a v4 only
box. This isn't "breaking v4 only setups". I can't think of anything
else that has happened like it, even.

I find it increasingly likely -- there are now v6 implementations for
all major routers, and most OSes of importance (including
windows). This was NOT the case up until recently. It is now,
therefore, possible to actually run in a v6 world.
