I second your concerns in principle, but I don't think you need to
worry about these features being anything but optional.  I suspect
that a majority of our user don't actually have the fine control over

Violating the RFC by munging From (for heaven's sake! have we learned
nothing from the sad history of Reply-To munging?) is simply not
acceptable for most purposes, although perfectly acceptable for
advertising. ;-)
