@HabitEXE I can only speak about teaching in general here (technical subjects in my case): as long as you're honest about what you're teaching and how, I think it's entirely fine to just teach whatever you are personally familiar with.
Ultimately that's what everybody else is doing too, regardless of what 'peer review' it might have had. It's just important to make sure that "your personal teachings" are actually the thing that people know they are signing up for, and that they understand the limitations of your approach (if any).
I've found that people rarely apply learned knowledge literally anyway, often they're just looking for someone who understands it to an explainable degree, in some version that's known-good enough to work as a baseline, and then they build their own understanding from there. Authoritativeness seems to rarely be expected.
