But Still, Why do polymer designer/Chrome Dev Editor still does not use syntax of polymer 1.0 and above.

New To Polymer.js

https://github.com/Polymer/designer/blob/master/elements/designer-frame/designer-frame.html and so on are using the 1.0 syntax. Where are you seeing older syntax being used in the designer specifically? Chrome Dev Editor is a separate tool.

This is true, the live site is very old now, but I've been resisting taking it down so that people still have access to their old projects. Maybe it's not that important though, as they still have them in gists.
