Security arguments aside (apple has infinite money, they can solve any problem that they want to and they regularly solve harder technical problems than this when it's financially prudent for them to do so), this is hugely anti-competitive.
My wife loves her Garmin as it's just a better sports watch than an Apple Watch, no matter what Apple say, but the integration with the iPhone is poor.
It's about time Apple opened up integration with 3rd party watches. They could still vet it with human-reviewed capabilities, the same as they do with Tap to Pay with iPhone and Family Sharing APIs, but they choose not to.
