There’s another school of teaching, where kana and kanji are banned for the first 2-3 semesters because they are a distraction to learn and internalize words and grammar.
I’ve met a few students of this textbook system when I was on exchange and my impression was that they were very skilled at Japanese for the amount of time they’ve been a student and what they told about their seniors was they pick up kanji fast, since they already know the words.
The big problem of course is that it is completely incompatible with other schools. Where do you place them when they go on exchange? With the n3 or n5 students?
Anyway, I always thought it was interesting that the exact antithesis of RTK* exists and works.
*RTK or “remembering the kanji” is a system that teaches all kanji before student learn their first word. It’s quite popular online as it lends itself very well to solo studying.

For those unaware, the OP probably means this three part series: https://en.wikipedia.org/wiki/Remembering_the_KanjiOne thing I have found over the years, I have never met a foreigner living in Japan who has used it extensively. (Many were aware of it, but few used it heavily.) However, there is a lively community of online learners who use it. (Don't read that as a judgement against using it; this is simply an observation.)
I was surprised to read this part:
> a system that teaches all kanji before student learn their first word
I have never heard this description before. I always thought it was a learning aid to use mnemonics to remember the meaning of individual kanji. If someone can complete all volumes of RTK before "learn[ing] their first word", I would be stunned. It would be a feat of super-human level of memorization and recall. That said, the Internet is a huge place with billions of people. There will be somebody, somewhere who took this path and is happy to tell you about their success using it.I have always felt furigana bridges that gap well enough in written learning. The downside is that it might become a crutch, but it can't for long if you are serious about learning reading. Native materials pretty quickly drop furigana.
Like with a lot of things like this, if you learn for long enough the differences in the major approaches work themselves out.
There’s another school of teaching, which bans all reading, writing, and speaking altogether in favor of exclusively native speaker verbal input for the first 6-12+ months of learning. Some YouTubers seem to like the idea of this, though sounds pretty extreme.
