What regulator would decline to ground a fleet at the manufacturer's request with good cause?

Yes, Boeing, as any manufacturer, is required to technically support their product, after they have taken any action necessary to assure safety.
Agree that in most cases such a recommendation by Manufacturer would get the attention of the Faa towards mandating an emergency AD (BTDT), but the FAA has additional requirements to live under before taking an action to ground a fleet. After all the manufacturer must have provided what they thought was a good enough fix else they wouldn't have offered it for an AD. In the end it's the operators who resist groundings as they convince the FAA that there pilots feel the fix will work for them.

When I thought a product fix was not available I could ask the FAA to restrict fleet operations under specific condition and the operators would push back to the point where they promised their own fix without an FAA restriction..

Lots of people in this decision process
