Heh, since we're coming up with alternatives, you can do it in
maya.api.OpenMaya too. Once you have the MFnMesh object you can check for
uv sets, and also check if the uv sets have uvs:
uvSets = fnMesh.getUVSetNames()
# Note that uvSets can be empty but that is also handled by the any()
function.
if not any(fnMesh.getUVs(uvSet)[0] for uvSet in uvSets):
unmapped_meshes.append(fnMesh)
