an interesting application would be chabad sukkas. since chassidim are as i understand , not to sleep there under any circumstances , is that a non-halachic-minhag overlay that doesn't abrogate this halacha; or, is the sleeping issur so strong as to make that not a function of a sukka lechatchila , and therefore irrelevant to the kashrus of the sukka....<div>
