I agree with that. 16-bit color helps a lot (but doesn't completely eliminate the risk of throwing away data), and the approach you mentioned (correction vs grading) is a valid exception to my point - though if you're doing that, you likely understand what you're doing and the potential gotchas. My point was more targeted toward the numerous tutorials I see where people use many such adjustment layers without real purpose other than to "play around" with the color, turning the image into a posterized mess (especially by stretching things too far one way, then essentially negating that adjustment with something else).
