... MAC addresses are just as forge-able; there are utilities on any
modern OS to let you spoof that. Moreover, if I have a machine that
*is* exposing a "real", legitimate, vendor-assigned MAC address,
I'm not sure I want to publish that to the world. At the least it's
telling anybody who wants to know what sort of hardware I'm running.
More generally, I'd prefer to opt out of any scheme that involves
creating an anonymized message ID. It looks way too much like something
a spammer would do. I know I've got filters that will bit-bucket
messages with all-hex message IDs; I'm probably not the only one.
