I think the main problem is that gnome-terminal is wrapped:

This is done automatically by ‘glib-or-gtk-build-system’, but obviously
it’s not so great here.

I suppose that in practice, it would work to simply switch
gnome-terminal to ‘gnu-build-system’.

Could you try that?

There may still be other places that add extra entries, though.
