@feld @7666 @phnt @lain in around 2005-2006 I wrote an entire pci-compliant company-wide card store for a big nonprofit, i wrote a great system that completely isolated cards from the calling program but still let the calling program do repeat transactions etc. my boss called it "too elegant" and requested a bunch of simplifications. years later the guy in charge of infrastructure architecture for the company comes to me and bitches about the design we're stuck with and says "it should have done x, y and z". and I told him "open the Word design document and go into the history and roll it back to version 1 from three years ago, there, it's designed."
