or we can even leave decision to users: if they want to use pygnulib, they can get it from pygnulib repo
That sounds to me like a very sensible way to go, at present. I'm also fine with having pygnulib inside gnulib, if (other) people want that. I just got worried that all of gnulib was about to transform into something totally different. I'm also not a principal developer of gnulib any more, so it would be nice to get more views from others (Paul, Jim, Eric, ... ?). Thanks much for your kind reply. Karl
