Re: WebKit, anyone?
I can answer that one for you: they wouldn't install it. Since this is a user-decidable switch, Apple could even add that to the features: turn on the lockdown mode and non-WebKit engines get blocked. This wouldn't be a problem because a user who wanted a different engine could disable it. The issue about engines is with choice. If you don't want any engine other than WebKit, then don't install one and you'll be just fine. You'll probably be in the same group as many others, including me, as I don't have a need for a different one given the tiny amount of browsing I do on the device. Others choosing to do so won't force us to.
