Given the spirit of C is at the heart of UNIX, not allowing binary data
to stdin and stdout would prevent compress, gzip, tar, cpio, and dozens
of other tools from working.  Even if it is within the letter of the
specification, anything that damages binary data to stdin and stdout I
believe to be outside of the spirit of the language.

Also, I can't think of any operating systems other than Windows that
don't allow binary data to pass undamaged though stdin and stdout.  Even
our boot loader gets this "right".

Piping the output of luac is useful.  I repeat my assertion that it
would be a shame if Lua was bloated to prevent issues with systems that
work outside the spirit.
