I started to learn Japanese 30 years ago, and in my experience the people who try to be smart and build systems almost never get decent. It’s procrastination while thinking they’re actually productive.
To add insult to injury this article hasn’t discovered anything new, makes it sound way more complicated than it is, and in the end still requires you to just remember which verbs are of the eru/iru group, and which are not (which was posed as a problem to solve in the intro).
Just make cards and mark the stem, learn it along with the verb. No need for heuristics. If you ever forget, you’re bound to remember the masu-form and can reverse engineer the stem from that 100%.
Agree. Experience shows that fluency arises when you don't have to think about rules anymore. My advice is to not spend too much time learning grammar rules (actually, no time, like native learners). Leave the rule discovery to your unconscious brain and get going with rote repetition.
Your brains "language module" is not a slow computer, computing rules, it's a fast lookup-table.

Do they have more fun than the other learners though?
Why would you expect the article where I’m describing what worked for me to “discover something new”? I’m literally sharing the mental model that I personally found helpful. There’s nothing “new” in learning or teaching a language. But this is the most minimal model I’ve found useful, compared to others, and I wanted to share it with other people.
I think you’re taking a lot of stuff for granted. “Just” do cards etc. You’re using the word “stem” but what’s a stem? Why do we sometimes inject -i or -a (or -wa) there and sometimes we don’t? You still have to learn that and understand that. That’s what I’m describing in the article. If you already know stems and how they compose with suffixes, congratulations, you won’t find my article useful.
The article could just be two words: ichidan, godan. Done.
Similarly, when complaining about how you have to memorize a big table of verb conjugations in the intro, the author links to a table of... -ta forms, a verb form for which the author later concludes you just have to memorize a big table.
