Makes sense... a full rotary with the sealing area less than an Allen “pinched” rotary.
Why not go all the way and combine the two for even less mass!?

As with other rotors which...
- feature a diameter considerably LESS THAN 2X the bore diameter, and
- feature round entrances/exits,
it seems to me that the material (marked off between the two parallel black lines unnecessarily adds weight (and the worst type: circumferential) and unnecessarily chokes down the bore even more than does a run-of-the-mill rotor.
...and yes, I understand that the lines I drew should have been curved, etc., etc...
bloke "...or maybe, I don't 'get it'...??"

Air flow similar to a piston?. Wonder if half [partial] valving effects are usable?
Pistons are very forgiving when fingering less than 100% accuracy.
When I play my rotor horns I hear my inaccurate piston fingers. Makes me focus on right hand [microseconds]timing. It takes a few sessions to become automatic.
Conversely going to piston horns from rotors, my precision is sort of on top of the beat and cleaner than usual.

Unless the routing is 3D, it seems to me that it's virtually a physical impossibility for the bore (through a rotor body that isn't even 2X the bore size, in diameter) to not be compressed into an ellipse (typically with a flat side on the exterior wall...ie. sort-of a "D" shape), and - if material is left on the exterior wall as part of the rotor body itself - the ellipse must then be even more compressed.
