why does bedrock and java has different texture pack systems? it would be cool and nice to somehow merge both systems for both versions of Minecraft.

such as

1. custom entity model for both (from bedrock)
2. custom item model for both (also known has Custom Model Data(from java))
3. use both systems together for custom armor

it would allow for customization for both versions that wouldn't been able to happen before and makes porting textures packs much easier without ruining the feel of the texture pack.

(I don't expect for both versions to be 1 to 1 with this)

(This is only marked for java due to being unable to mark it for both)

(also I think the issue type thing is bugged I can only mark this as a bug)
