Consider:

Such situations occur during refactorings and code evolution.
The import is no longer used. Should the compiler flag that as
an error, or leave it be?

I'd use a warning, as with unused variables: the code is in an OK
state when in the middle of a work (such as temporarily
commenting a block), but less OK for a release.
Also, Visual Studio highlights unused includes for C#, which is
nice.
