IMO "let's replace Sender" schemes are broken
by design.  If you know a good place to note
that an existing Sender MUST NOT be modified
please do.

But there are situations where an existing Sender currently IS modified,
that being regarded as good practice.

The best example is where the message is being forwarded by a mailing list
expander (or, equivalently, it is being gatewayed into Netnews). Those
cases are customarily justified on the grounds that it is a brand new
transmission (even though the original Message-ID is retained).
