This package would house new plugins that we would wish to add to common_plugins until they stabilize (have no Major bug Issues etc). This would give the rqt user a better idea of what plugins we are presenting as stable and fully developed. It would also help keep the number of issues on the main repo down so it is clear to users what bugs and enhancements we are focusing on. Less important but it might be wise to have a distinction between the really critical core plugins and the "nice to haves". rqt_core_plugins could house rqt_console, rqt_image_view, rqt_plot and all the other "it is significantly harder to use ROS without a tool like this" plugins. rqt_common_plugins could house things like rqt_msg, rqt_srv, rqt_action and rqt_web that are useful sometimes but something you could live without.
