Request #27802 has been rejected by alerque [1]: There is no reason to *delete* VCS packages just because upstream doesn't recommend them for everyday use or even make any garantees about ever commit even compiling. Nobody is forced to use VCS packages at any given point and they are free to use stable packages too. But VCS packages do have their place and there are times when they are useful. Since they don't need constant updating anyway they can be left around to be handy when that time comes that some unreleased fix saves the day or a user wants to play around with some prototype feature.
