Comment (by chrisvanpatten):

 Support for % widths would be nice, but that introduces a lot of
 complications with embeds, because you'd have to recalculate the height
 every time the browser width changes so the embed scaled correctly.

 As I think about it more, I'm starting to agree with the folks who suggest
 ditching $content_width entirely. On responsive sites—which are becoming
 more and more the norm—$content_width is pretty useless. Yes, it affects
 the editor width as well, but on a responsive site, you're essentially
 making a promise to the end user that the content will look a certain way,
 when in fact there's no way to guarantee that.

 I know it probably ''won't'' be removed, but I'm not sure it's worth
 migrating to the `add_theme_support()` style either. Seems like too much
 work for too little gain, especially in the age of responsiveness.
