Yes, I should have used the word “easy”, not “obvious” - indeed, it’s quite deterministic, which is great, and if you call those 5 bullet points “easy”, sure. But I agree, with an LSP it’s easy, and the documentation links make it easy to SEE the code, if that’s all you need. So… I’m a happy camper. Just thought I’d concur with the frustration that a.b.c.d is not all directory names until you get to d. 
I think you’re misunderstanding the complaint. We’re not saying we want to understand everything and it’s difficult. We’re saying that trying to understand one part forces you into trying to understand everything, and that’s not practical.
