I really think this is exaggerated a lot. Maybe we don't use a lot of complex features, but at sugarlabs we have written a whole desktop environment and app ecosystem based of gtk3. We use the python gtk3 wrapper and I think there was only 1 instance this year where gtk3 broke our ui (icon_size got removed or something like that). We also use a lot of other gnome things (eg: gsettings) and those don't seem to be an issue.
