iOS WebKit Debug Proxy in Appium 2.0

I could not find any option in XCUITestOptions() class, or the desired capability to include the port for webkitDebugProxyPort capability.
It is also no longer available in the appium server flags as I checked with appium server --help

I found two issues related to it which suggests that this is no longer needed to run tests on safari in iOS real device or to use web-views.

Appium 2.0 updated docs also does not suggest that this change has been implemented.
Could anyone confirm if indeed we do not need webkitDebugProxyPort capability in appium 2.0?
