PAM functionality questions

Hi,

Just reviewed the PAM FAQ, and have a few questions (https://social.technet.microsoft.com/wiki/contents/articles/33363.mim-2016-privileged-access-management-pam-faq.aspx)

1. FAQ states: "You cannot require multiple approvers; only one PAM approver is needed" - from a distance, it looks like PAM is a component of the MIM Service, so why can there not be multiple approvers? This will be very limiting.
2. FAQ states: "The approval process does not allow references. For example, you can not require
   approval of the caller's manager" - again, it appears that PAM is part of the MIM service, so why are reference attributes for approvals not supported? This will definitely be very limiting.

Thank you,

SK
