Reminds me of the "Tractor Story".The nudist colonies that I'm familiar with require you to place a rag down on public seats or clean them thoroughly after using them due to some public health concerns regarding emissions.
I think it would be reasonable to recommend at least scant bottoms in some contexts because of this, just enough to cover up the parts that can contribute to health hazards when you're sitting or laying down somewhere public, because it would be mildly less of a hassle than the constant cleaning of seats and used rags.
That's really the only concern I have on the subject, though.
