It can be a code smell, but there are legitimate uses. This is not something that I would ever "ban".
Over-eager code analyser tools are themselves a "smell", in that you either justifiably or unjustifiably don't trust your developers, trying to make up for their real or perceived deficits with a rather dumb tool. That never goes well in my experience.
