Never ever? I wouldn't mention it in the resignation letter like in the OP but it's been very natural for managers and colleagues to ask where I'm going next and I've been happy to share. I also ask colleagues who are leaving where they're going next and I never saw it as a problem. Then again, I've worked with mostly reasonable people.
