Hmm... that's a good question. To that I will argue no, there is no such thing as a "good kind of nesting" in any programming language, even for markup.
I would like to expound on the specific case of HTML because deeply nested markup can be an indication of a poorly planned layout structure teeming with so-called "CSS hacks". On the discussion of performance, deeply nested markup also takes it toll on the amount of memory the DOM consumes. All those wrapper divs may seem innocent at first, but having a bunch of them will definitely be taxing for lower-end devices, especially on mobile.
For data-oriented nesting such as in XML and JSON, perhaps I can be more lenient, but even then, deeply nested markup requires a bunch of computer resources just to traverse, not even at the data processing stage yet.

We're a place where coders share, stay up-to-date and grow their careers.
