I have a lot of blocks so I have decided to create multiple registries to keep things more clear:

public final class FruitBlocks {
	
	private FruitBlocks() {}
	
	public static final DeferredRegister<Block> REGISTRY = 
			DeferredRegister.create(ForgeRegistries.BLOCKS, ExperimentalMod.MODID);

	public static final RegistryObject<FruitPlantBlock> ORANGE_PLANT = 
			REGISTRY.register("orange_plant", () -> new OrangePlantBlock());
  
    /// ... More fruit blocks are registered here
			
}

 

This is another registry but for different group of blocks:

 

public final class MachineBlocks {
	
	private MachineBlocks() {}
	
	public static final DeferredRegister<Block> REGISTRY = 
			DeferredRegister.create(ForgeRegistries.BLOCKS, ExperimentalMod.MODID);

	public static final RegistryObject<Block> TERRAFORMER = 
			REGISTRY.register("terraformer", () -> new TerraformerBlock());

    /// ... More machine blocks are registered here
}

Everything is working as expected, but I am not sure if this is safe thing to do?

Is there a smarter/better way to separate groups of blocks/items/entities?

There is no official way from Forge, you can use the way you prefer. One Class and separate the types with a new line, a global Block class with sub-classes for each type or separate Classes as you already use it

over read the question 😅

the only thing you need to mention is that you should not put the DeferredRegister and the RegistryObjects in separate Classes. This means you need to use a new DeferredRegister for each class, if you use sub-classes you can ignore this. 

If you use one or more DeferredRegisters for Registry should not matter. But um not 100% sure about that.

@Luis_ST, thank you for the quick reply.

I was just worried that I might be using Forge mechanics the wrong way by creating multiple registries of same type, but if it is safe to do, I will stick with that than.
