Comment here if you want WaniKani to add 5 more levels with the remaining Joyo kanji

I agree. However with custom WaniKani scripts this isn’t neccessary. We have things like [Web] WaniKani Custom - The WaniKani SRS system but with your custom words and vocabulary for that! And if you don’t like that, just add whatever you need to Anki? You can even set up it up to have similar pacing to wanikani.
