Custom Block States

I think an important tool for data packs would be the ability to add custom block states. Custom block states would not do anything by themselves (except show up on the f3 screen). If a player wanted to make a custom block state they would have to specify the following in a JSON file within the data pack
-The name of the state (most likely as the file name),
-The block(s) it applies to,
-The possible values for it,
-The default value for it.
If the player wanted to give it a model they would have to do that separately in a resource pack and if they wanted to give it purpose they would have to use functions.
If two data packs implement a block state with the same name I see two possible solutions, either the data pack loaded later would take precedence or block states would have their namespace as a prefix.

  I think this is greatly needed for the data pack developer community to allow new blocks to be generated without overriding old blocks. It is a shame that this is not already in the game but I'm sure there are quirks to implementing this that would be too big of a time investment for the Mojang team.

  If they add things like this I'm tired of using ItemsAdder or plugins to modify minecraft with pure limitations such as textures, model sizes, rotations of the same that brings an integrated system would be more than an improvement.

  It would be enough just to create a block: CUSTOM_BLOCK with 1 million free block states

  This won't work because of how the game caches all the possible blockstates into RAM when the game loads.
  Your PC would explode.

  You can test it by downloading the Minecraft sourcecode, creating a custom block, attaching an INTEGER blockstate attribute which has 0 to intmax possible values.
  The game will just freeze and RAM will be filled.

  It would also allow players to make a datapack that adds things like log rotation to crafting tables & furnaces, which would be cool.

  This is an absolutely necessary addition, as currently there is only ways to override blocks that have existing vanilla blockstates, whereas with custom block states you could still have the normal block, and then when the block state is switched you would have the "custom block" (similar function to custom model data)

  The only thing that would be needed after that would be the ability to call block states in the (block).json loot table file, allowing for fully customized blocks that drop the block with the custom block state, basically making a fully functioning new block
