How does the developer story get better if you're required to support many web rendering engines on iOS instead of one? Or is the endgame that you'd just point people to Chrome/Blink and extend the web monoculture to Apple devices too?

The endgame is that Apple is forced to actually make a working browser, rather than intentionally starve it of resources to benefit the App Store. Everyone wins.
