FWIW, I kind of like the idea of getting rid of it completely. Is there really ever a good reason to set it to something different than that? If not, well, we have too many GUCs already, and each of them carries nonzero performance, documentation, and maintenance overhead.
+1.
There are plenty of cases I think where it doesn't really matter with the values, but when it does I'm not sure what it would be where something else would actually be better.
