I can't give an objective assessment of whether it has increased or to
what extent.

Thanks for pointing out an objective symptom, though: munging of the
message ID values in various fields.

The resulting broken threads are a constant source of annoyance. I don't
know whether any one host is the culprit, or whether there are many
hosts that are munging the message IDs.

What you've demonstrated is that at least one host is violating
communication standards by altering existing reference fields on
messages in transit.
