The Cues rear derailer lacks any slant to the parallelogram, suggesting that it is 1X-only. As well, such wider ratio cassettes like an 11-50t go right up against any modern derailer's wrap capacity without even having more than one chainring.
But a double might be coming if new front and rear derailers arrive, and with the cassette being limited to perhaps 40t or so (same situation with Shimano's GRX group).
You could be right about the significance of the lack of slant. My guess was that the lack of parallelogram slant is a tacit acknowledgement that the conventional slant design is good only up to some maximum cassette slant angle, maybe corresponding to 12 to 34 teeth or so, with cassette sprockets up around 50 teeth making much too steep a slope.
But has anyone tried one of the new non-parallelogram Shimano derailleurs on a cassette with a large sprocket of 28 or so? Maybe the new non-parallelogram design is tweaked in some way that makes it work just as well as the parallelogram design on narrower-range cassettes.
