It seems like this may be more of a platform issue. As I mentioned earlier, MacOS (not just Safari) used to hide the placeholder as soon as the field was focused. But iOS didn't, and now neither does MacOS. So the convention is different between different versions of the OS, and used to be different between the mobile and non-mobile versions of OS X. 

By the way, :disabled is another situation where an author may want to change the text color alpha without changing 'opacity' on the entire element. And that is clearly not a pseudo-element.
