Well, if you're asking if apple execs use that setting, the answer is probably that they don't.

I think the issue is that there are SO many piled up little features everywhere that SOMEone is using that keeping everything working while making any changes at all is very difficult.

I am a fan of more wood behind fewer swings. Don't add something like spaces unless you think you've got something so good that you are confident that it will be the common path.
