Will the unsupported lookups be addressed in a patch, soon? We use these today on most of our projects and we are excited to push for 15.3 before end of year - this could be a showstopper. Also, the 'view level settings' - may not be a show stopper for these, but lacking 'required' capability will impact our data quality - something that some fight dearly for, preferring data quality over all the other benefits of the new UX (and, they have a valid point).
