I agree that it doesn't make sense for a wire-level protocol to impose
MUST requirements on the user interface of user agents.

To give a concrete example here, imagine a in-dash navigation unit in
a car that uses HTTP to interact with a real-time traffic service.  If
the navigation unit receives a 307 redirect to a POST request from the
traffic service, does it really make sense to prompt the user?
Prompting the user might be dangerous because it might distract the
driver and cause him or her to crash the car.
