That's not correct. For example, imagine the issue indicates Symantec, but
it requests EV only (via a Symantec-defined issuer-parameter), and you
receive a request a DV. What do you do then?

Similarly, if the Forum introduces issuer-parameters regarding the use of
3.2.2.4 validity methods, what then?
