One interesting use of symbol versioning could be just adding a single
symbol version to all symbols in Gtk+ (and stack) for 3.0. This could
get us part of the way towards supporting linking Gtk 2.x and 3.0 into
the same app (not something I recommend, but possibly useful for weird
stuff). Of course, there will still be some issues with that, like the
gtk3 gtypes having names that conflict with the gtk2 ones, but that
could theoretically be fixed.
