Default Why is the Verizon stock keyboard missing key function

I know about Swiftkey and Swype -among others, but looking for answer to stock keyboard question.

On other carriers it seems you can turn the settings cog to the comma (which I use a ton).

On Verizon note3 keyboard you cannot turn that to comma.. Option simply not there. So frustrating!

Also, why the hell don't they allow long press interval shortening
