It would be, but I don’t actually think there’s demand for that. I don’t think that’s what the user in that thread is asking for, nor have I seen anyone else request it – the (note) style is used far less than full notes in the first place, and I suspect most/all of those users are fine with the ibid/just author version.
The multiple requests and discussions about naming were, I’m pretty sure, all for full note with shortened subsequent notes. So I’m happy to add this style if we have a sense that people actually want it, but the number of CMoS styles is already confusing and a drag to keep updated the way things are, so I’d wait until we actually know it’s needed (in the sense of requested with any frequency) before adding it.
