To be clear, I don’t really have a problem with getting a 2.79+ edition as a sendoff for the 2.79 series. I just wanted to point out that making a 2.79c or 2.8 this edition wouldn’t serve this purpose.
The only point in having this stable versus experimental build setup is to provide users with a more bug free version of blender to use. If they were to promote what is currently experimental as the next stable it would defeat the whole purpose of having this setup. They would have to promote a final edition as some sort of special edition in order to prevent confusion.
We should also keep the fact that anyone can build blender in mind. It would probably be better if an outside developer made an ultimate 2.79 build that has all the features the current stable 2.79 lacks. That would help prevent confusion that could come from an official 2.79+ edition. They could even mix in experimental stuff from other people’s builds like that radial array modifier, the fracture modifier build improvements, maybe even some UI tweaks.
edit: it looks like there already is a third party build like this:
