PAM session start had to be called from two procedures (one for interactive, one for non-interactive login), and then closed. The latter required keeping session state in some variable all over the login time and it created several problems how to do this in a nice and secure way. In general, using the PAM session management required much more effort than other authentication methods and it was simply skipped by the developers. However, I don't remember exact details and many things could have changed in recent PAM versions.
