Ability to: Start small with a shitty demo which can get buy-in from other folks on a team and continue pounding out high-impact features in no time first, to sell the invention to anyone. Then get this demo cleaned up to the point it ships with docs, tests, telemetry in production, and there are no bugs and crashes. Just couple of improvement requests. And when this thing can be enabled/disabled dynamically, and enhanced/expanded for the future without major rewrites.
