Can TAC Lite use Term Reference on a User?

This module is excellent. I have one nagging curiosity however: why I am not able to use the very same Taxonomy terms I just created and simply "tag" the users?

In using Drupal 7 I am creating some views to go along with my taxonomy access. For example : a list of "Teams". I use tac_lite to define what members of those teams can see and do. Then, I wish to show lists of those teams. Great. can do that by listing terms. Say I have two teams: Red Team and Blue Team.

Then I wish to display users who belong to a team. I went to setup a view to: find users with term id = "Blue Team". The data is not stored as a term reference though. It appears to be saved in the user data blob field. Now I have to create another term reference field.

Is it possible to have the storage mechanism use taxonomy in the same way for nodes and for users? Create terms. Tag your nodes. Tag your users.

Perhaps it is not that simple? Or at least, allow a setting, or hook where I can tell the system: Also add the selected taxonomy term(s) to the user.
