There was a function that would give you a monotonically-increasing build number that you could compare against the build that any given feature was added in that people should have used, but there was also a function that gave you the name of the OS, and lots of people just checked if that contained a 9. The documentation explicitly said not to do that because it might stop working, but the documentation has never stopped people using the wrong function.
