I hate this knee-jerk response so many have that copy/paste == bad. You aren't in any position to create a generic API until you have at least 3 implementations

I hate this knee-jerk response so many have that copy/paste == bad. You aren't in any position to create a generic API until you have at least 3 implementations, so unless it's a very obvious solution service, or you are practising some kind of extreme waterfall, copy/paste could be the best way to go. I'll hypothesise that most of the architectural problems we have are down to the cult of prefactoring.
