Lower the mob spawn limit when the simulation distance is low

In the Bedrock Edition, my initial simulation distance is 4 chunks on my device (I don't know if this varies by device), but I'm plagued by the problem of mobs (including enemy mobs) spawning ridiculously frequently. Since caves where mobs spawn are absolutely necessary for game progression in survival mode, I currently have to change the simulation distance every time I create a world, otherwise I can't even play survival mode, which is not only incredibly annoying but can also cause lag on lighter devices like smartphones. If the idea of ​​reducing the mob limit based on simulation distance has somehow never crossed your mind, I think it should be implemented immediately. Or is it such a difficult change systemically? In any case, please do it as soon as possible.
