Not sure if intended feature, but when creating a BUD switch, it can be set off by placing a redstone object (repeater facing piston, torch, Redstone dust) on the ground one block distant from the piston, which theoretically should not have any power or set off a detection. With any other block, the switch is not set off, but it is with a redstone item. https://youtu.be/yYY6a8_g5sM this video shows me performing it, and its reproduceable in all of the versions I have tried it in so far that have slime blocks. Is this intended?

Not intended, but Redstone Wire causing too many updates is a very old issue and tracked here: MC-81098
4 years ago, when the first rendition of the Observer was added, one could see this very beautifully: Demo video 10/2016 The demo starting at 0:39 is imo especially scary : ))
