In essence, this "smart" behavior is already built into CSS1 [1]:

  "The 'width' has a non-negative UA-defined minimum value (which may
   vary from element to element and even depend on other properties). I=
   'width' goes below this limit, either because it was set explicitly,=

   or because it was 'auto' and the rules below would make it too small=
   the value will be replaced with the minimum value instead."

I.e., UAs should be smart about this no matter what the value of the
'width' or 'clear' property is.
