I think your example describes a situation, where given the design
of the package, warping makes sense to preserve the user's sanity.
In general though, there are few situations where the design space
is so limited that warping is necessary/desirable/acceptable.

As a window system implementor (and user), warping strikes me as
bad manners (mainly because it usually violates the principle of
least surprise).

I receive many requests for the cursor to be warped for convenience
in the requestor's favorite situation(s).  The problem, of course,
is that the notion of "convenience" varies by situation, requestor,
and phase of the moon.
