For now it's available in ULS, it's unlikely for it to be redeveloped elsewhere.
Niharika, not all known bugs and enhancement requests are filed in bugzilla, can you please file them? They'll then need to be triaged to identify which are blockers for the feature to be default.
The feature was added to BetaFeatures on March 2014, so there is time until September or it will vanish, if I understand correctly.
