While I agree that doing nothing gives Tesla nothing to work with, what's uploaded to Tesla will be dependent on the triggers they have defined (I think there are around 250 of them as of a few months ago). If a manual acceleration event at a 4-way stop is not a trigger, nothing will be sent to Tesla.
I've been monitoring my network traffic. I intervene often with FSD, and on some days, nothing is sent to the mothership despite those interventions. Pressing AP snapshot guarantees a giant upstream push from the car. And then some days without any pressing of the AP snapshot, the car will upload a ton of data, indicating that something in my drive hit a predefined trigger(s).
