I think perhaps an alternative could be to make stockpiles harder to select. You typically don’t want to select your stockpiles anyway, except in the somewhat rare and typically non-recurring case of changing the settings. Perhaps it could be that you only can select stockpiles if you first explicitly go into zone mode. The same with trapper regions. I tend to make somewhat large ones, and a couple of times I had to explicitly scroll away with the camera in order to deselect what I had selected (I’m strange and tend to want to have nothing selected if I’m not doing anything or looking at anything) because the floor where my camera was pointing was taken up entirely by the trapper zone.
