There can be difficulties in how the 'sky' vector gets applied I think.  Say
the camera is on a Ferris Wheel that also turns around the y axis too, if
the camera doesn't rotate along with it (stays aligned to the ground plane
for instance, as if seated in real ride) then nothing is apt to go wrong. If
it follows the Ferris Wheel path as though afixed to it then it might flip
from one orientation to the next.
I'm not sure of the associated problems but I have seen what appears to need
consideration as far as the sky vector goes.
