Because of their shared ancestry, I would assume replacing WebKit with Blink in Safari is quite easy. Once we start reaching Blink monoculture, expect Blink-only feature use on the web to sharply increase. This could mean Apple switching to use Blink for Safari as well, just like Microsoft did with IE Edge. If we can learn anything from when IE6 reached monoculture in early 2000s (e.g. 96% market share in 2002), its development velocity sharply increased and the web site developers adopted the resulting IE-only features in abadon (stuff like XMLHttpRequest date from this era.) Some of these features were later standardized, but large swaths of the web remained IE-only for the next decade and more, even as competing browsers surpassed IE in performance and features. I am afraid Blink development will likewise accelerate and web site developers will adopt these Blink-only features as if they were web standards. Only this time, building a competing web engine looks unlikely due to the sheer complexity to ever achieve feature parity with Blink.
