If all untrusted headers are removed at the edge, we don't need an

The "authserv-id" field servers as an identifier. It can be used to
identify where the header was added within the ADMD. For example,
there may be two or more verifiers running on two MTAs performing
tests. If there is header reordering, we can still identify where
the header was inserted. Obviously, that depends on the format of
the authserv-id being used.
There are several "status" header fields in use today. Although they
are meant for internal consumption, they do leak out. It's quite
common to see two different sites using the same header field name to
convey the same type of status. That's one more reason to build in
some uniqueness into the header.
