Fair enough of a point. Web components have a lot of potential and it&#x27;s good to hear Mozilla et al are slowly helping build consensus on the custom element instatiation! Polymer is one opinionated take on Web components which feels a bit heavy handed for my taste, I&#x27;m experimenting with x-tag from MSFT lately. Much lighter weight. The nice thing once these specs get finalized it&#x27;ll be much easier to mix and max from whatever components you like (if they follow a DOM centric approach).<p>One thing that&#x27;s still frustrating is the lack of html rel import in Firefox. Any word if that&#x27;s ever going to change? Http2 changes the performance constraints quite a bit so the previous decision not to support native html imports means you have to use vulcanize and you can&#x27;t dynamically mix and match sources.
