Actually, this is probably something that needs to be done gtk-rs-core as it also fails for soup3-rs's MessageHeaders. Both seems to be fundamental types.

It is implemented for shared types https://github.com/gtk-rs/gtk-rs-core/blob/04bddc004bb165fbfce92249357ab2a6dadcbf21/glib/src/shared.rs#L178-L196

Nothing would work otherwise :)
