In general I think that the more information, the better. Mentioning reference implementations, or even just open-source portable software, seems like a good idea to me. We won't have room to mention every implementation, of course, but I don't see why that should stop us from mentioning the important ones. > I will be happy to contribute either as an editor or reviewer if > needed. > Best, > great, thanks.
