Earlier quoted context omitted.
I think GP meant "the minority browser we bend our logic for, in order to accommodate"
Yes, that is what I meant. I have to work on a lot of e-commerce websites and the WebKit browser engine is the one that seems to always be late to the party or outright won’t support new features. But of course most shoppers on a website are on mobile Safari, especially the ones making purchases. And there’s nothing anyone can do about it because Apple won’t allow other types of browser engines on iOS.
(Of course usually when one delves into exactly what features Safari is missing, specifically the ones which piss off web developers, it’s push notifications. And to that I salute Apple for bravely holding the line against that nonsense.)
