I was referring to Safari here. I'm aware that WebKit is cross-platform, but it has vanishingly small market share if you ignore Safari, and it doesn't provide sufficient competition to browsers based on Chromium/Blink to keep the web from being a monoculture.

Safari doesn't help here because it's proprietary and only runs on one family of OSes. WebKit doesn't have any substantive market share without Safari.
It's unironically better than Chrome in nearly every way, except dev tools.
