Comment (by caseymilne):

 Is there any way that styles from themes that apply to these blocks could
 be repurposed by the editor without having to specify them? Meaning could
 we make it easier for a theme to just focus on styles for the front-end,
 and then the editor has a way to grab those styles and parse them if they
 conform to a a certain structure, such as wrapping them in comments like:


 {{{


 /*
  * EditorBlockStyle
  * block-target: paragraph
  */

 h2 {
   font-size: 1.2em;
 }

 /* /EditorBlockStyle */

 }}}

 Then the editor would need to open the theme stylesheet, parse out all the
 block target sections and combine them into an editor stylesheeet.
