That's not a problem in that I know I like to see them to give me a
"heads up" that something is coming down the pipeline soon.  I don't
think anyone has ever complained of this before, do you?

Having this happen only once (maybe twice) in a over a decade really
isn't that bad of odds.  We have loads of embargoed security patches
that properly include the cc: stable tag, yet don't leak the patch to
the public mailing list.  So this really is a rare thing to have happen.
(also when it did happen, no one except me seemed to notice it, which
was pretty funny in itself...)

We still have whole subsystems that have yet to learn about how to put
proper "cc: stable@..." in their patches, why do we want to change the
muscle memory of those that are doing the right thing to now have to do
something else?

So I don't think we need this change, let's just keep things as they
are.  If more and more people get sloppy and mess up, we can revisit it
then.
