Probably a little of both. For one I think it's more of a nerdy feature. It's not that discoverable. It's maybe like a keyboard shortcut on the Mac, if you know it's there is really helpful, but most people never use them. Also it's probably used less each day than anything else, but I may argue it goes less noticed. I find myself using it as reflex at times and missing it without noticing I'm pushing too hard on the iPad. So while I don't think it's essential, I do think it's helpful and I get a benefit from it daily.
