Well, you can just disable the system WebView implementation — that's what I did first. To my surprise, of all the apps I use, only Skype stopped working so nothing of value was lost. And as it's a webapp anyway, I could just open it in Firefox.
Then I decided to tone down my paranoid stance a bit and replaced it with Bromite. At least it has User-Agent randomization which makes tracking you a bit harder.
