The usual IETF model is to define a core capability that has the minimum functionality to do something useful. Everyone claiming to write code that "supports" the specification MUST implement all of that functionality. Everyone. Whether operators choose to use all the features is a separate matter, but as Mark notes, there is a problem if the initiating side uses it but the receiving side does not.


The usual IETF model lacks a policy negotiation layer which is why it
has been impossible to perform any changes to deployed protocols.

DKIM is based on a policy negotiation layer that provides for the
missing mechanism for feature negotiation.

This seems like a pretty idiosyncratic use of the word
"negotiation". Is a sign posted on a fence stating:

"Trespassers will be mauled by rabid Pit Bulls"

count as negotiation? The DKIM signing policy is much
more of a public notice than a "negotiation", IMO.
