It creates a perverse incentive to deliberately do things a more expensive way at the beginning and then be a hero 6 months down the line by refactoring it to be less expensive.
Ha ha, software developers already have this incentive. Viz: "superhero 10x programmer" writing unmaintainable code to provide some desirable features, whose work later turns out to be much less awesome than originally billed.
Of course the truth is more complicated than the sound bite, but still...
