It doesn't support a *compact syntax for providing multiple densities
for variable-sized images*.

This topic has been brought up over and over again when discussing why
srcset isn't sufficient.  Please see <http://www.xanthir.com/b4Su0> -

Yes, this is fixable through the 'content' property and proper
indication that you're creating a "replaced element", rather than just
filling the element with an anonymous piece of content.  Then "height:
auto;" will work as intended.
