Yes, NCEES (the body that administers the Engineering licensing exams nationwide in the US) is discontinuing their Software Engineering exam next year because only ~80 people have taken it since it was created in 2013.

I think the biggest problem they had was that despite having the exam, not many states actually issue Professional Engineer licenses in the Software Engineering discipline. Because of this, I don't see why anyone (in those states) would bother taking the exam if they can't actually get a license and use the title "Professional Engineer".

I forgot licenses were by state. It's probably also the case that software engineers don't normally have to "sign off" on things for regulators in a formal way as is the case in other areas of engineering. So, other than having a title to stick on your business card, taking the PE exam doesn't buy you a whole lot whereas it's virtually required for other engineering branches.
