Well, this is fundamentally where we end up disagreeing. Within the timeframe of a single mobile app development cycle, the entire coding infrastructure of the world changed. Our collective day-to-day coding experience has morphed within 15 months.

Here, you're making a negative argument, it "can't" be done. Maybe. Historically, correct. I prefer to image what could be done. As insane a statement as it sounds just 15 months ago, a small dev team could get it done, I'll stand by that. Framing is up to you, to each their own!

Even getting through the discussions and negotiations with the 3 big game console companies to support their platforms can eat up so much of your time window. You can't really vibecode your way out of that - though I suppose you could generate your email responses or an AI meeting participant and risk blowing up the business relationship.
