If a hypothetical real Chrome for iOS existed that -- like this thread is about -- let you run native quality apps with access to features that Safari doesn't allow then people would switch over. Imagine actually getting notifications from your apps!

If they don't like the UI/UX, I'm sure they'd find hypothetical Chromium variant that suits their needs. Eventually browsers without better underlying technology would just cease to exist.

I use Firefox myself but if it stopped keeping up with modern web standards eventually I'd have give it up.
