I'm proposing that the 2822 syntax should be extended to allow arbitrary

Received: and Resent-* fields.

   At first blush, this seems like a very good idea. There are a number
of things which are trace-like; and forcing them into the non-trace area
tends to confuse the ordering of the non-trace headers.

   OTOH, there _might_ be some existing MTA this would break, though I
can't think why...

It might confuse software that analyses Received: fields, causing it to
fail to find all of them. However there is plenty of software out there
which already interleaves other fields amongst Received: fields, so robust
code already has to cope with it.
