Sympa does too, in the X-Sequence header by default.

mailman2 and mailman3 maintain a message number ("post_id") internally
and will include it in the subject prefix if configured to do so.

That's what I have in mind.

Yeah, the message number isn't always _exposed to subscribers_ by
default.  Agreed.  However, it is _tracked_ by default.  (E.g., the
"increment the number by one" code lives in the MLM's code, not in some
random plugin's code.)  Thanks for refining this point.
