which is why I didn't do anything so idiotic as to define narrow as "not
my group". But you could very reasonably argue that "wide" equates to
large numbers of users and narrow to a few. Whereas, what I had in mind
is wide equating to diverse and complex uses and narrow just to the
popular simple uses. You can send an email and switch to a calendar and
lookup a web page with a simple interface comprising a few gestures, but
you can't do complex technical tasks efficiently that way.

I think this is the crux of the matter. The "world of computing" has
been joined (swamped?) by millions of new users with new devices that
can't be used for complex tasks (which those millions would not think of
attempting anyway). And the GTK project is adapting to this "big
league".
So, I think you may have answered my question "Where do we go?": we will
have to revert to Gtk2 sooner or later. 

I guess the problem is that if we continue to offer a Gtk3 version the
GNU/Linux distributions will want to build against ever-newer versions
of Gtk3 with resultant problems like the one that started this thread.
