why not use the extends= syntax you mentioned?

<my-button extends="button" attributes>Push</my-button>

because browsers that don't know about web components wouldn't pay any
attention to <my-button>, and render "Push" as plain text.

  Browsers that don't know about web components will fall back to
<button> with <button
this-is-made-much-more-marvellous-by="my-button"> (or whatever)

However, this fallback will only really be useful for very simple cases, where web components have been used to jazz up what essentially is still the element that was extended. And, I would posit, any scripting that was done to act on the all-singing, all-dancing new web component button (if it does anything more than a regular button) would not work for the fallback. Unless it's really just using web components for fancy styling (for instance having a "material design" button that essentially still works just like a button) - in which case, it makes more sense to work on stylability of standard elements.
