One nice thing about this functionality is it could also be used to force members to change their passwords. If you change the 'm_password_compat_scheme' field for a member row from "" to "temporary", they'll be forced to change upon their next login.
This could be done quite easily in Commandr, e.g.:
Adding a new member with a temporary password, does result in a member with a temporary password
A member with a temporary password will be told they need to change their password after logging in
A member with a temporary password will be taken to where to change their password after logging in
Bulk adding via CSV members with temporary password enabled, does result in members with temporary passwords
This could be done quite easily in Commandr, e.g.:
echo temporary > /members/bob/m_password_compat_scheme
