Not only that, but once the company owns it, they'll want to start managing it, making changes, etc. You run the risk of it becoming bloated with features, making it harder to maintain and the whole thing loses the reason it existed in the first place. Maybe that's a stretch, maybe not.

Also, if it does decreases work time by 3/4, guess what happens when the business finds out? Deadlines and estimates get pushed up, and everyone is expected to get that much more done. Sometimes, as a developer, you need a trick up your sleeve to keep your head above water fighting unrealistic expectations. If everyone has the same trick and it becomes part of your SDLC, the goal post just gets moved.
