This is a great point. I'm really happy about Apple's plans, but I have a hard time taking it at face value that there's nothing to worry about here if there's resistance to putting that plan into the spec itself. Because I start to get suspicious any time a company says, "we're not going to do X, but we absolutely refuse to commit in any meaningful way to not doing X." There's an implication there. I feel the same way about syncing, honestly: "Everyone is going to support 3rd-pary sync." "Can we put it in the spec that they have to?" "Well, that would be overreaching..." I think there are a lot of people who have genuinely good intentions, but it still makes me pretty nervous. If we could just trust every company to magically work things out and be compatible with everyone, we wouldn't need industry specifications in the first place. I think it's appropriate to try and standardize the baseline mechanisms users should have to control their keys and preserve their privacy.
