Anyway, it's just my 2¢ and it's up to the maintainer of the plugin (which, even if I fixed a bunch of big issues I'm not), and for myself I don't really care as I use GTK3 but for testing purposes anyway.
A new plugin doesn't need the permission of the maintainer of the GTK2 version, so if @pmjobin submitted a PR for a whole plugin it would be up to @frlan `</ shifting responsibility, management 101>` :grin:.
