Hi there,
It shouldn’t throw any errors – there’s not really anything to “use”, it just sits there in the background.
It won’t hurt anything keeping it in there, that’s for sure.
There’s a couple functions to remove some of the main parts, but some other parts are baked into the core theme and not really removable.
