The immediate issues I see are:
The bulpup arrangement gives it a moment arm that would bend your wrist rather than push into the palm of your hand on recoil.
Even if your wrist is fine, the hot gasses escaping the cylinder would be directed straight into your forefinger and thumb with every shot.
Finally, a break action or flip-out reload would now use space occupied by your hand around the grip. Not to mention a break would require the trigger and hammer mechanisms to be on opposite halves adding complexity and potential reliability issues.
I see we've just completely abandoned semantic versioning. Not a good look for the future of major or even just cohesively themed updates.
