But the key question (from the Webkit bug) is really whether the UA
styles apply to the input itself or a pseudo-element inside of it.
If the UA style is
input:has-placeholder { color: ... }
then, as far as I can tell, there's no point to styling the ::value.
If the UA style is
input:has-placeholder::value { color: ... }
then you get the same cascading result as with an input::placeholder
pseudo-element (styles that don't select the pseudo-element don't
change the UA default), but with the addition that authors can style
the input in other ways.
