@andyholmes there’s a map model in GTK; a bunch of stuff should be moved in GIO, but GTK still moves faster than GLib, which means we can fix API warts faster—like the fact that list models take an unsigned int instead of a size_t for the index

hm, I guess I should have non-variadic versions of adw_message_dialog_add_responses()... I didn't bother initially since it's a helper.

@alexm It's entirely up to you if you want to add a vector version and annotate it with `(rename-to add_responses)`, or if you want to leave re-implementing `add_responses()` to language bindings

I mean I can add it, it just seemed like bindings wouldn't need it in the first place, just as nobody is using g_object_set() etc there.

@alexm Most people will likely use multiple add_response(), but I'd expect languages like Python or GJS to add overrides to provide the equivalent "iterate over a list of tuples and call add_response()" convenience method just to minimise the differences with the C API
