Allow creating a Family group without auto-enabling location sharing for every member; let users opt-in individually.

Let's be honest—the reason I want this is because I HATE the way my family members name their devices, and they keep devices on their list that they no longer own. I want to control if I see this crap on a person-by-person basis rather than being forced to see "Mom's iPhone (2)", "Dad's old iPad", and other poorly-named or outdated devices cluttering my Find My interface.
