Internet-Draft draft-gondwana-dkim2-header-01.txt is now available. It is a
work item of the Domain Keys Identified Mail (DKIM) WG of the IETF.
It states:
Note that we have not included a version number. Experience from [IMF]
onwards shows that it is essentially impossible to change version numbers.
If it becomes necessary to change DKIM2 in the sort of incompatible way
that a v=2 / v=3 version number would support, we recommend using header
fields named DKIM3 instead.
I agree it is too hard to change version. However, when you query for text
fields, several domains return all sort of records, defined with * labels. A
v= field in the beginning is very practical to quickly discard extraneous
stuff. Perhaps we could call it /verify/ and have just v=DKIM2, where 2 is not
the version...
