Yes, I’d love for her to put out a more robust program with an actual work book, because that makes such a huge difference. She also seems to mostly focus on making the most crucial skeleton of the language understood - the elements and concepts that keep affecting all of grammar. It’s not like you can follow her channel and then sit the N1, but for me, I could follow her video course and pick up Japanese reading. 
She has two or three episodes where she added some homework sheets, but either stopped doing that, or restricted the homework assignments to be only for her Patreon supporters. I keep not getting around to joining Patreon to contribute, though, so I’m not sure.
By and large, yes, I agree. But apart from setting up for some potential unlearning like you mentioned, I feel like people sometimes walk away with weak spots in their most important fundamentals. Or, at least, I did when using the more “conventional” sources, like Tae Kim.
I feel like the whole が and は issue is a bit unclear at times, for example.
But this could just be my overall grammar ineptitude talking.
Seriously… English grammar as well as grammar in my native language - I can use it, but I’d fail elementary school tests where you’re supposed to " dissect" a sentence and name all the grammar constructs at work there.
That’s why I can’t ever seem to shut up about CureDolly. I find grammar intensely boring, that snowballed to me having poor knowledge of grammar terms, which in turn snowballed again into me being quite lost at even exceedingly basic explanations like “が marks the subject.” Ah, yes… of course… the subject. I see.
I barely know this stuff in my native language, let alone English.
So if you’re like me, and grammar tends to beat you up behind the bike shed and take your lunch money; try CureDolly.
