Yes, the patch-id is a heuristic. It's really a very good heuristic in
practice, though.

Also, if the argument is "it might not always work", I still claim
that "99.5% useful" is a hell of a lot better than "_maybe_ useful in
the future, but known to be painful".

Because that's the trade-off here: people are arguing for something
that wastes time and effort, and with very dubious use cases.

But yes: please do continue to add links to the original email - IF
you thought about it. That has always been my standpoint. Exactly like
"Fixes", and exactly like EVERY SINGLE OTHER THING you add to a commit
message.
