This has definitely given me a better way to phrase my current coding style than "on-demand" or even "lazy" coding. Basically, the way I work is: I build what's being asked for, and no more. I try and anticipate where future demands might come in, and build things such that there is "room" for those features, but I don't build them before somebody asks for them, even if they just take 5 minutes. 5 minutes of dev is also 10 minutes of debugging and 15 minutes of testing, and that adds up quickly.
