I agree with you, Bill. Lately, I have started a more conscious consideration of dodging and burning, at the stage of negative exposure, and I try to optimise negative development to make its printing easier. What I mean by that is that I may indicate N+1 etc even if I have enough overall contrast (so otherwise N), but if I would like to add local contrast, which could be a bit harder to increase through local print manipulation. Having very recently discovered selective masking (for dodging and burning) and masked flashing, I am happier to be "accessing" parts of the straight-line of the curve which were previously too hard to burn or dodge, and therefore necessitated overall, global contrast adjustments. So, in some way, I would expect to need ZS less, but, on the other hand, it helps me decide what I want to labour on during printing.
