Step 1: Have the iPhone pop up saying "do you want <Pebble watch> to be able to send messages?" and let the user decide which devices can send their phone messages.
Step 2: Have the iPhone pop up saying "do you want <Apple watch> to be able to send messages?" and don't just assume "yes"
Both steps would improve security, even if they harm Apple's profits.
I absolutely hate these sorts of nagging popups and I’m happy that a vendor I already have to trust doesn’t pop them up when I acquire a new product and sign it into my Apple account.
Imo, if this were to happen, it should happen by allowing devices like the pebble watch to sign into an Apple account and acquire permissions through that process rather than nagging on my phone on pairing.
