I just wanted to report that this incompatibility means that CocoonIO is no longer compatible with C2 games for WKWebView.
I have contacted CocoonIO requesting a refund for my subscription and they have confirmed they cannot do anything about it since C2 is at fault for not supporting their service. -_-
Now, if Cordova's preferred method is the correct one, then obviously CocoonIO's is the "hack/work-around" and it's their fault... either way, this is a major problem moving forward for any iOS developer that wants to use CocoonIO. Basically, they are stuck with crap Canvas+ or worse WebView.

That work-around doesn't work anymore, it disables WKWebView and defaults to Webview mode only.
/facepalm
ps. I've been testing Intel XDK WKWebView and so far it's functional, though there's major issues with audio/music. But at least it works.
