   What if you want None to be able to apply styles added to the <head> to the whole page? Or if you want style descentant elements from a component while maintaining encapsulation from outside the component.

   @zoechi I never meant to disable the option completely. Obviously, there needs to be a way to control style encapsulation.

   My question is why isn't there an additional (and possibly the default) option that is ViewEncapsulation.Auto that will automatically detect whether native ShadowDOM can be used.

   The currently default value (Emulated) is making sure that native ShadowDOM cannot be leveraged even when it does supported.

   I see. I expected Native to fall back to Emulated if not available.

   @zoechi, I doubt that's the case. Also, the documentation doesn't state so (where it really should).

   See:

   angular/modules/angular2/src/platform/dom/dom_renderer.ts

   Line 109 in e7470d5

   nodesParent = DOM.createShadowRoot(hostElement);

   Ok, than it's good you created the issue. I hope my questions helped make it more clear for future visitors what the issue is about instead of obscuring it ;-)

   This should now be easier after #7883 has landed.

   it's not possible because the behavior are not exactly the same (there are edge cases)
