This makes perfect sense, and in fact I see that "Almost right angle
buildings" is still in my JOSM validator option list, and still
checked.  I don't know what caused the rash of building squaring that I
saw in NYC -- perhaps the sensitivity was adjusted at some point? I
haven't had this validation error come up in my own work for a long time.

That's a good way to describe a lot of iD's effects in general --
mappers become living bots implementing the iD devs' ideas, under the
impression that these are the official recommendations of the OSM project.
