Sure, but both halves are still there. WebKit is just filling in for Blink.
> but it's not "Google's wildly popular web browser".
You want to know the screwed up part? It actually is. There’s no gun to Google’s head to list any web browser at all for iPhones in the App Store, but they do, and they themselves chose to brand it exactly the same as their desktop and Android browser; and that’s exactly how people perceive it: Google Chrome. It’s also wildly popular. I ask people about it sometimes when I see them using it and all that geeky crap that you and I know about how it’s not the same as Google’s “real” browser is beyond them. They don’t care and it’s just Google Chrome to them.
> It may be a functional web browser (honestly arguable given how old and buggy the iOS rendering engine is)
WebKit is still a top class rendering engine and only about as buggy as any other rendering engine. Blink is of the same lineage given it is a fork of WebKit and Gecko is even older.
