I think it is in 2.3 (actually, the glue overlay is
backend_check_restrictions() aware, and there's a(n almost) general mech
to delegate controls checking to the appropriate subordinare/overlay.  I
don't think backporting to 2.2 is an option because, although not a big
dela, it impacts many portions of software, and may incur in heavy string
comparisons with current 2.2 implementation fo controls handling.  2.3 is
more efficient because controls checking is implemented in form of direct
access to the registered controls array.
