MC-44632Lock NBT tag does not prevent any hopper mechanics
When I decided to test some locked chests, I noticed that a hopper both going in and taking items from a chest with the
{Lock:"My lock"}
tag, don't get blocked by the lock. This removes much useful functionality since hoppers could easily take and steal items from these locked chests.
What I expected to see:
No items being transferred, possibly items would be transferred into hoppers that shared the same
.
What I saw:
Items were transfered and not blocked in any way, any hopper could change the container.
Steps to reproduce:
Take a container that can be locked, use
/setblock ~ ~ ~ chest 0 replace {Lock:"My Lock"}
Put a hopper above and underneath the chest.
Put items in the top hopper
Watch them flow into the bottom hopper, passing through the chest just fine.
Environment
Windows 8.1

Is this still a concern in the current Minecraft version 14w10c / Launcher version 1.3.10 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
It still happens in 14w10c.
The only purpose of the Lock tag on blocks with an inventory is to prevent player interaction with them.
"Removes much useful functionality" - I actually find this extremely useful for my datapack.
