Yeah, if someone's avoidance of what they consider shitty code leads them down the path of dancing with future hypotheticals it's a problem that needs to be fixed. Not by embracing shitty code, but by fixing their criteria for shittyness. Non-shitty can be full of elaborate dance moves with those hypotheticals, but most likely it's not. Non-shitty always stays clear of bug magnets though, and badly performed dance moves clearly are bug magnets.

As are "it works, so it must be good enough, right?" implementations, when it only works for circumstantial reasons. Code that would fail on encountering single-digit hours is still shitty code even when it works in 0-23 instead of am/pm and happens to never run before noon.
