[webappsec] Cascading style-src onto font-src in CSP

As I was thinking about the frame-src, worker-src stuff, I remembered:

 A last year's TPAC in Lyon, we had Jonas Sicking visit us, and came to
rough consensus at his suggestion that, if font-src wasn't explicitly
specified, it should take the value of style-src, if specified, before it
takes the value of default-src.

 I notice this isn't in the current 1.1 draft.  Did this just get forgotten
along the way because we forgot to track an action for it, or was it
deliberately rejected?  (it would've been the first and only
multiply-cascaded directive)

  Would anybody like to jog my memory, or give their $0.02 on the matter
today?
