It's extremely common to mess that up.  This would be even worse in
some ways, since it would only be relevant for a small minority of
elements (inputs with placeholders set).  And because it would be so
uncommon, when it *would* come up, normal authors would be unlikely to
know the correct pseudo-class/element to fix it.  So I do think it
would be valuable to not require extra declarations from authors.

On the other hand, the problem will only come up if the author uses
placeholders *and* colors inputs, so its practical impact is limited.
And of course the author will see it during even cursory testing,
unlike relying on default background-color.  So it's not really
critical, but would be nice to have anyway.
