Well, I would not add this getter to ContentBrowserClient as 1) the browser context lifetime is different so this property can return NULL and it could lead to errors because people might not anticipate it 2) BrowserContext should be obtained from web contents, so there should not be need to introduce an extra getter for it. 3) At the moment only Android needs RuntimeConext getter, I guess XWalk-android code should be fixed rather than the getter added.
