Block Entities for addon creators

i think i speak for a ton of creaters when i say this but please add tile entity support

they could be just like a block but instead they use a entity geo wich means you could use animations, animation controllers, and render controllers! also they have support for dynamic properties!

there base block could be a block.json so they can use states and permutaions but they could also 

have some extra stuff like minecraft:inventory and other ones as well, so please consider this idea!
