Given that the Media Queries spec is in CR going towards PR, what's the avenue
for specifying this?  Simply include it in CSS3 Writing Modes?

So @writing-mode would instead be:

  @media (writing-mode) { 
     /* styles used when writing modes are supported */
     .rounded { border-radius: 2em 1em; }
  }

Is that what you're imagining?
