I think it's problematic in buffers that are supposed to be analyzed
mechanically by external programs.

A couple of weeks ago there was a scenario where I could easily have
been bitten by the bug: I was working on some code which reports error
locations as a file position + an offset in lines. When debugging that
code, I first went to the file position in the source file, and then
used `C-u NN C-n' to see if everything's working out correctly.

When the buffer happened to contain wrapped lines, I'd have got to the
wrong line, making me think that the error reporting code was at
fault. It would probably have taken a while before I'd have found out
what's actually faulty.
