Yeah, good point, about the breaking change. TBH it's not even that necessary, I did that because I intended to have cutn_attributes as an argument to the backends (and I just attributes felt too ambiguous), but that's not the case in the final approach I took. For GeneralState, leaving it as attributes is alright, so I'm going to roll it back.
