Exec chains are used for software packages - they're portable, easy, and
simple. qmail, qmail-ldap, twoftpd, curier, curier-imap,
sqwebmail, fgetty, all use these for authentication just to name a few.
Easy to debug, easy to set up, and run on almost any Unix.
Can you say the same about PAM? Didn't think so. Who says you can't
apply the same approach to OS utilities?
