> I feel like there’s some kind of miscommunication, and I can’t bridge it, which is driving me a little crazy. I genuinely don’t understand why it’s bad that I wrote something for people who don’t want to depend on fluently reading kana for learning conjugation rules.

I didn't say it was bad. That's the miscommunication. You're taking it personally when people give you advice, and interpreting it as criticism.

(I mean, some people here are probably being obnoxious about it, but that's genuinely not my intent. I said at the very top of my first comment that if your method works for you, great! It's a completely normal part of learning to create explanations that fall apart with additional experience. For whatever it's worth, in the process of writing the previous comment, I looked up some things that refined my own understanding of the linguistics!)
