Doug, I totally understand and support the issues with maintenance. I do, however, have a couple of questions: 1. Have all ports been preened of dependence on rcOG? 2. What about 3rd party software that is not in ports? Would it be possible and acceptable to officially deprecate rcOG in 5.1 and then remove it sometime in June or July? I understand that this extends the maintenance of rcOG a tiny bit, but it will also help users and vendors transition. Also, will any seatbelts be in place to catch software that tries to do things the rcOG way? Thanks!
