CanDestroy:["minecraft:command_block"] does not work

commandblocks are only destroyable in creative, works as intended
proof: switch to survival, you still can't break it, it's like bedrock

It is always "works as intended". Don't be so lazy guys, help us players make the game a little bit better!

this WAS posible to break in previous versions, but it was changed, so that players wouldn't break the redstone in the maps

Edit:
why do you even want them to break it, you can easely pick another block

I want to have the >possibility< to choose if players are able to break it. Should be disabled as default but you should be able to enable it with the CanDestroy command.

I would want this because I am a redstone and cmd block contraption inventor. This would open so many possibilities, like for example custom ores or lucky blocks without a plugin. You just make random cmd blocks spawn in the world and since players can't change the code inside them anyway, you could make a compressed command (activator rail, minecartCommandBlocks) to do random stuff and destroy the block with setblock air afterwards. It would be nice if players could pick up these lucky blocks again (of course also in the first place) if someone places them infront of their house, so they do not have to trust in their luck and activate it (by putting a button to the side and pressing it) to get rid of it (because they are lucky blocks, they could also spawn 10 creepers).

It is just depressing that you are limited every now and then (MC-53347 , MC-52819 , MC-52958 , MC-31365 , MC-9661 , MC-53928 , MC-54716) in this beatiful sandbox game and it seems mods have too much to do to look into the problems longer than 10 seconds (or not even that) and just go for the easy option "works as intended".

I am a commited player and reported a lot of bugs (like the ones above) to help mojang make a better game and none was solved or some not even viewed.

Just my opinion.

what the CanDestroy tag does is in will make the player in gamemode 2 able to break the block like in survival, if it isn't breakable in survival, in it isn't breakable with the CanDestroy tag
