Ionic-platform-web-client

Hi,

I had an existing project, I just switched to the new ionic-platform-web-client! Everything seems to work, but I have one question. Is the ionic-core.js still necessary? I think so, because when i comment the lib in index.html my app breaks. But I’m not sure if I had missed sthg. else, because when I check the console, I got following messages twice:
Ionic Core: init ionic-core.js:466
Ionic Core: searching for cordova.js ionic-core.js:145
Ionic Core: init ionic.io.bundle.min.js:2
Ionic Core: searching for cordova.js ionic.io.bundle.min.js:2

???
