Ionic2 WebView vs Crosswalk

Hi, I searched something in the new documentation for ionic2 if there is something about alternative browser but I found nothing about Crosswalk.

My question now is, whiches are the advantages and disadvantages of the two technologi. I think there is still the “problem” of the bigger package size of crosswalk.

What does the ionic team recommend to use? Can the team open here a discussion or an explanation of this topic?
