So we're back to this then.  Do you also object to websites saying "404 not found"
while still logging the fact that you tried to look at a resource?

Sometimes you want to keep the junk that was sent to you while saying to the
sender that nobody got that message.  Making that hard within the standard will
just cause people to work around it by doing things like capturing all mail that
hits the MXes before sieve processes it.  Not providing a facility because it can be
used to lie doesn't change that.
