My $.02, in the time that I have been maintaining pam in Debian this policy
of ignoring PATH from pam_env has never been discussed with me. And I do
not think there's any reason to consider cron "special" as a service such
that it should diverge from the default system path as set by systemd/pam -
any such divergence is simply a bug, as seen in the case of /snap/bin.
