Before Quill implements this, you can achieve a similar behavior via pure CSS (Example). You have to tweak the style though e.g. increase the placeholder font size if the current format is heading.

@luin yes, thanks for you suggestion. I'm just not sure it's good idea for me to write custom definition of empty text, base on quill inner structure. But, of course, as a workaround it should do it.
