I brought them up because I was considering supporting them, but decided 
against it because the vast majority of the exit codes are outright silly, 
and it's not really that easy to do boolean operations from shell scripts.

It's zero and nonzero.  The rest is optional.

It's zero and nonzero.  The errno was convenient.  We output a text message 
with the details anyway.

If you like, I can change it so that our exit code is always either 0 or 1.  
That's about 95% of the interesting information right there.  If it really, 
really bothers you, I will do so.
