This is the case at least with apps from Mac App Store. Safari uses WebKit2 which is a private framework. If you want to ship your app on Mac App Store you have to use WebKit1 which does not support split-process model. Flags that enable GPU accelerated compositing are also private on Lion.

Why would an embedded web view be slower than Safari on a Mac? Mac OS doesn't have the restrictions on generated code that iOS does.

Plus he could always embed WebKit or Chromium.
