I'm one of those people who would want this. I still enjoy coffee but since quitting caffeine several years ago I've become hyper sensitive to it so even decaf can potentially keep me up. It would be nice to have a decaf that was even more decaf, then I can have coffee whenever I want without worrying about my sleep schedule. I definitely recommend tapering off caffeine, it's actually extremely powerful when you're not slamming your body with 250mg at a time for years on end. Getting used to lower and less frequent doses before quitting was a lot less unpleasant than trying to quit when I was still drinking coffee and energy drinks all the time.
