Rather than

  <button is=my-button></button>

you want


that just gets all the <button> goodness through composition/inheritance.

Also the fact that you need <form is=my-form> to be able to submit
custom elements is something we should fix in the design of <form>.
That is="" can make certain hacks a little simpler is nice, but that's
not enough to justify standardizing it. I have the feeling we're going
in circles though, since the arguments on both sides have been made
repeatedly for the past x years.
