Forums / Cotonti / Support / User profile tags missing

I'm just trying out Cotonti with my old skin which was for Seditio.
Obviously there's a few changes that will need to be made to make this skin 100% compatible, but i notice a few tags missing which ive used in users.profile.tpl

{USERS_PROFILE_EXTRA1_TITLE},{USERS_PROFILE_EXTRA1},{USERS_PROFILE_EXTRA2_TITLE},{USERS_PROFILE_EXTRA2}...etc used to be available but no longer seem to be in the core user.profile.inc.php

Is this intentional, or should they be reinstated?
