It doesn't need to follow Windows or Android's UX, but it should be allowed.
Something like a settings menu where you can control the default apps for many "intents" (that's the android terminology, not sure what else to call it).
Choose an app for email, sms, "instant messaging", browser, navigation, phone, etc... Don't let individual apps change anything, and if you want don't even let them prompt you to change something. That last part can be enforced by appstore guidelines.
If apple does this, i'd switch overnight. And as someone that is about as far away from the apple ecosystem as you can be, i'd probably end up using many of the apple "things" over time. Let their first party apps stand on their own. I have no qualms with having theirs be the default, and it honestly doesn't even bother me if they aren't un-installable, but let me change my defaults!
