Yes, this is the intended approach for the HSK/TOCFL lists I created. Students are recommended to work their way through a given level before looking at the words for that level in my lists. I’m not in any way claiming that these words are more important than those that are in fact on the lists.
Actually, it would be possible to study HSK and then a frequency list at the same time, then proceed roughly twice as fast in HSK as in the frequency list, which would achieve much the same result as my project here. The only problem would be that you’d get hundreds of items you already know (but don’t need to add) or things that aren’t words (I discarded all those manually, see the original article). In a language other than Chinese, this wouldn’t be necessary.
