I agree to a large extent with both the perspective that you should stop reviewing, and that you should continue reviewing.
Obviously, if you continue to progress, at some time you should stop reviewing. If you've become an advanced Japanese learner with good knowledge of the readings and compounds of the joyo kanji, you're not going to go back to RTK1 and go, "Well, better refresh myself on how "six" is a top hat with animal legs!" That would be like building a temporary scaffold, building a skyscraper, and going back to tinker with your scaffold.
At the same time, if you finish RTK1, and you say, "Phew! Glad that's over! What's next - maybe 8 months of pronounciation practice and and Tae Kim grammar!" That's no good either. That would be building your scaffold, not building your skyscraper, and letting your scaffold rot away.
So I think it's important to have an RTK exit strategy - and that probably wouldn't be RTK2&3 either, which are mostly more scaffolds.
The two viable follow-up strategies I can think of are either transition to attempting to read kanji in context and build your skyscraper, or delay the collapse of your scaffold by continuing to maintain it. Probably for many, it'll be a combination of both, with reading being a priority for those who are picking it up quickly, and RTK review a priority for those who are learning kanji reading at a slower pace.
