(Bedrock Edition) Optimize Minecraft Entities

I have been looking at entities like in depth and I'm convinced that currently in 1.10 the way they are being handled inefficiently NBT wise by the game. An example is a trident entity that has a variant nbt tag, why does a projectile that has no variant behaviors defined in the behavior file json need a variant tag that's just for starters but there tons and tons of other tags that are never used for that entity and it's super inefficient. 

I'd wish this was addressed in 1.12, 1.13 or 1.14 this would optimize the game a great deal by my calculations ruffly 20%+ storage space on most if not all entities.
