Well sir, I would say the largest client flag exodus from the mainline implementation in bitcoin’s history since and possibly exceeding the UASF ? Is that the “evidence” you are demanding?

If there would be demand for this change, nodes could already change that. But on the contrary a significant portion of the network even changed proactively their node implementation.

How about when pro change propaganda posted by reputable people like Calle get ratiod by the masses? And what steps have Core taken to learn if there is a mass protest? They should care right? Your question implies it would be important if there was such protest.
