Not quite sure I see Apple being willing to spend resources to make Windows less of an unpleasant cesspool, and even losing business if a few people, thanks to Safari, find it tolerable and don't switch to Apple.
Apple sure wouldn’t mind gaining more Windows converts. But it hasn’t been their core strategy for a long time. They do care about Safari being supported by websites—and thus by developers of those websites—so the browsing experience on iOS doesn’t suck.
Apple will produce another Windows version of Safari if, and probably only if, they come to believe it’s an important and necessary developer target. For now, they probably rightly believe otherwise… whether that’s because developers are using and/or testing in Safari on Apple devices already, or because their efforts targeting Blink are sufficiently compatible.
