@mreid-tt I've added pygobject to all python-wheels packages without checking arch limitations (if any). Let's see if things build ok to confirm all really is good.

Also from my reading (claude.ai), in practice, for cross-compilation, we should use --introspection=disabled (or provide pre-generated introspection files from our target sysroot), since running full introspection in a cross environment is complex and usually unnecessary unless developing bindings.
