Support, this has the potential to save a lot of grief - especially as shulkers are a popular method to store rares or grass in. I can’t see any problems with this, only benefits. It would help prevent other visiting/ invisible players picking the shulker up by mistake.
Support. I have seen this cause problem numerous times, especially when visitors pick up spawners that other people break.
Seems simple to do, but for now all you have to do is move it using a piston and it should instantly drop.
