I strongly disagree. Implementation of a draft specification is useful to establish a proof-of-concept and perhaps (especially if there are multiple independent implementations), to unconver potential ambiguities in the draft specification. Implementation is not however a good indicator of protocol soundness. This might have been sufficient in ARPAnet days, but on the scale of today's Internet it is necessary to perform extensive analysis and review - neither of which have been done for DKIM. So no, it's not appropriate to raise the bar for changes on the basis of existing DKIM implementation. At most, the charter should specify that new DKIM signatures be distinguishable from signatures made according to the old DKIM specification.
