How much does it bog down? If for the next two years you're adding features at half the rate but you got a five year boost you're still head and some of that work can simplify the situation.
Yeah that's the thing, it's hard to say how much you are bogged down. As time goes on the value of the 1.5x multiplier increases in value, but then you also run the risk of massive spaghetti code (more or less, depends on what the genie considers good).
I don't know if there's great value in trying to figure out if you would quantitatively get ahead though. I think the value is in just realizing that some groups are inclined to perhaps take that risk, and some groups are not.
If your code has increased by 3x, that means 2/3 of the entire project is unknown to your developers. It’ll take a lot of work to just get everyone across that much extra code. To say nothing of how much work it would be to tame it.
I agree with the GP. Business people would probably salivate over this, but if it were up to me I’d want to say no.
