buries the lede, at least for Stanford. It is incredibly commonplace for students to "get an OAE" (Office of Accessible Education) exclusively to get a single room. Moreover, residential accommodations allow you to be placed in housing prior to the general population and thus grant larger (& better) housing selection.
I would not be surprised if a majority of the cited Stanford accommodations were not used for test taking but instead used exclusively for housing (there are different processes internally for each).
edit: there is even a practice of "stacking" where certain disabilities are used to strategically reduce the subset of dorms in which you can live, to the point where the only intersection between your requirements is a comfy single, forcing Admin to put you there. It is well known, for example, that a particularly popular dorm is the nearest to the campus clinic. If you can get an accommodation requiring proximity to the clinic, you have narrowed your choices to that dorm or another. One more accommodation and you are guaranteed the good dorm.
There's a point where it's not immoral to leverage systems available to you to land yourself in a better situation. Avoiding increasingly-overcrowded housing situations is I think one of them.
If Stanford's standards for these housing waivers are sufficiently broad that 38% of their students quality, isn't that a problem with Stanford's definitions, not with "cheating"?
Once you grow up, you realize your parents were human, made self-interested decisions, and then told themselves stories that made their actions sound principled. Some more than others, of course.
