That doesn't by itself make it a silly idea.  It just means that
glibc-based systems where the user has set (e.g.)
_FORCE_GLIBC_STDIO_BUFFERING to the value "line" would not be
conforming. Since such an option would not be mandatory (or the
default) this is not in itself a reason not to support this.    But of
course it would make all scripts which rely on this behaviour
