“If this is a good idea for web browsers, why stop there? Why not mandate the same sort of choice screen for every app? Mail, Calendar, Notes, Weather — why not require all of them to show a choice screen for picking a “default”?”

Gruber is speaking sarcastically, but this would be legitimately good for third parties competing with Apple apps, and as a result, I think it would be good for Apple users too, who would benefit from greater competition and more choices. https://mastodon.social/@daringfireball/112051267962275699
