Simple reason here was that we don't have any left to spare.

;-)

(unless Phil bumped from 0-9 to 0-99 when I wasn't looking...)

We are already oveloading more of them than we would like to.

In any case, what would it gain, code-wise?

The $domain conditional and the $local_part / list match workload is the same 
either way, and the header *can* be left in place for later vetting/analysis, 
or 
stats. Once the acl_c/m has been actioned/NOT it goes back in the bit-box for 
recycling. - it is no longer visible as a header can be.

So the header has better after-the fact confirmability.
