    I agree.  Yet, the following looks silly:

I seem to recall previous discussions have suggested that the "v" tag shouldn't have been included in the first place; if things are so different that you need to change the version, you may as well change the name of the header field altogether.

Seems like six of one, half dozen of the other. The version change sort of signals that it has a backward incompatible change, but everything else will be the same. Not much of a reason, but it's not like it's harmful. It seems easier to produce the document too, since a new header would probably need to copy in all of the DKIM text and people implementing it would need to comb through it to make sure that there aren't other changes they missed. Again small, but not nothing.
