I suppose I should repeat the answer, too: one xdg_output maps to one
wl_output and has a unique name.

It doesn't always make sense to think about connectors. DRM might have
them, but many compositors also have other backends like X11 or Wayland.
wlroots names those too (X11-1, WL-2, etc), but they aren't connectors
and don't have a monitor model.

I don't think there's any amgibuity. One xdg_output == one wl_output,
this much is already clear by the existing semantics of the protocol and
we needn't go any further than that.
