Unless keys are queried through a different mechanism?

(Given the desire to allow extensibility in the choice of query mechanisms, it

The DNS name *registration* mechanism is inherently essential to DKIM.

The DNS name *query* mechanism is certainly going to be essential to initial
operation, but is it an inherent requirement long-term?
