No comment on the rest of your claim, but this is a silly argument.
The standard says the same thing about at least fcntl.h, signal.h,
pthread.h, and ucontext.h, which clearly are useful.

It was meant to be tongue-in-cheek :).  Perhaps I should not have assumed that everyone else was as familiar with the POSIX documentation; I figured that most readers would know that most pages say that.

But, that was the result of a string of many different searches attempting to find someone explaining why this was a good idea or why anyone would want to use it.  I think in this case, it's accurate.
