A lot of people use bluetooth devices - watches, headphones, car, speakers, etc. It makes much more sense for the toggle to only temporarily turn off bluetooth because in today's majority use case, that's what people are likely wanting. It sucks that you have to deal with it for your minority case, but that's just the way things are. There are work-arounds, but you clearly don't want to try any of those. You're prerogative. And Wi-Fi is more efficient than cellular. It's best to use that as much as possible.
