There are several popular libc variants on Linux. Which of them is official?
Also, Linux is not POSIX compliant and doesn't necessarily care about being. There are several important IO options on Linux that have nothing to do with POSIX.
Making libc the stable support boundary has all sorts of advantages to an operating system and basically zero downside. Only vanity argues for doing it the Linux way.
