FWIW, <picture> is significantly different because:
  1) Still images already work *natively* in browsers and WYSIWYGish  
editors using <img> since way back when.
  2) Still images don't require an elaborate scripting API.
  3) From an authoring perspective the marginal cost of switching  
from <img> to <picture> is incredibly bad considering the marginal  
utility. (To go from a string fallback to markup-enable fallback, you  
break the compatibility with over a decade of software for the non- 
fallback content. And normal authors care about non-fallback more.)
