WhatsApp specifically needs phone numbers, and you can filter out which contacts you share, but not which fields. So if you family uses WhatsApp, you’d share those contacts, but you can’t share ONLY their phone number, WhatsApp also gets their birthdays, addresses, personal notes, and any other personal information which you might have. I think this feature is pretty meaningless in the way that it’s implemented. It’s also pretty annoying that applications know they have partial permission, so kept prompting for full permission all the time anyway.
