I don't understand why you keep calling this a hack. It's part of open() contract, and I'm quite sure that it was a deliberate choice to declare O_TMPFILE as O_DIRECTY|new_bit. See for example this comment:

I wrote a patch to explain that it's fine to call open() with O_TMPFILE on old kernels to check if the flag is supported: see attached patch.
