The parts of Postfix that you can play with are documented. The
bounce(8) service protocol and internals are not documented,
therefore you cannot play with them. Only the documented behavior
has a promise of backwards compatibility.
That said, the Postfix pipe(8) service already maps exit status
codes to text as per /usr/include/sysexits.h. If that text is not
what you want then you can override it with text on stdout, as
documented in the pipe(8) manpage.
