Yep.
Director or Final frequencies are possibly the worst places (not that any other frequency is the right one) to start a conversation about Your aircraft energy capabilities, especially around very busy intercontinental airport. Anybody flying in radar controlled busy airport terminal areas knows that You will be very likely assigned speeds on final approach, so better be proactive and include during the briefing what speeds You are able to make at the estimated arrival GW with current weather forecast, and adjust the figure (i.e. 180 kt to 6 nm) once You are getting to finals and are aware of your tail/head wind component. In that scenario, probably "Unable, we can make 170 kt to 5 nm" (that is basically 180 kt to 6 nm) would have worked wonders. For sure JFK controllers are in some cases not easy to deal with, but You need to come up with a plan anyway.
