I think a new feature which teaches players about several openings would be very helpful. I know there is opening explorer, but something interactive like in studies is great.
You can find lots of studies that can help you with learning/studying openings here:
lichess.org/study/topic LeninPerez has lots of studies about different openings - although it is best for you to get a coach to help you study openings.
Yes, there are studies about different openings, but I think a separate feature for it would be nice
An opening repertoire is opinionated and as such I think community studies are the best tool.
In other words, if your feature was to be implemented, who decides what to teach and what not?
