Hi Phil,thank you for your review! I saw it quite late, because I thought I was automatically subscribed to this bug.
As for your comment at "1. Build", I intentionally didn't use these substitution variables because in /usr/share/doc/gobject-introspection/README.Debian.gz at "3. Runtime dependencies" it says:
* Add ${gir:Depends} to -dev packages if they contain GIR XML * Add ${gir:Provides} to -dev packages if they contain GIR XML And there is no GIR XML in this -dev package. Regards Gabor
