I agree; nothing really uses sysexits except inside sendmail perhaps...
It has been around for more than 40 years:

^As 00062/00000/00000
^Ad D 1.1 81/10/15 20:29:54 eric 1 0 
^Ac date and time created 81/10/15 20:29:54 by eric

and one would think that if it was useful, it would have caught on by now.

I think that it is best for most programs to use EXIT_SUCCESS/EXIT_FAILURE
instead except for ones like init(8)...
