I believe this was pushed prematurely. it was causing crashes when AQ
was disabled, which I've fixed with revision 1ba7a0a0742b, but it also
changed a great deal of outputs even when the feature was not
configured, which was not expected.  So the next commit ff5e67b4a60a
backs out the implementation (leaving the API in place for now) until
these issues are resolved.

If you want to evaluate this feature, please checkout 1ba7a0a0742b.
