Thanks, but I meant why Vue does not use that custom tag name in build process, is it because of better support in old browsers? or something similar. Any thought on my second question ?

Hey, Why Vue doesn't use custom tags (like some other frameworks) and and prefers changing it into div or any other valid tag ? (actually I'm fan of this method) And my other q : Since I'm Ember dev too, Is there any plan to create anything like EmberData in Vue too? cause that's awesome and really helps in big projects.
