sysexits is actually nothing more than the documented exit codes for
sendmail(8).  Practically nothing else uses them, except procmail
scripts, postfix filters and similar where you need to know if sendmail
(or another MTA's drop-in replacement) succeeded - and even those
usually only check for 75 (EX_TEMPFAIL).

I think we have one or two utilities with documented exit codes other
than 0 and 1.  Everything else just returns "0 on success, and >0 if an
error occurs"; we even have an mdoc macro (.Ex -std) for that exact
phrase.
