Good design is as much a function of intelligibility, which in turn is a function of a variety of human factors and local context, as it is about flexibility under changing requirements. Given two equivalent implementations, one more elegant but also more reliant on knowledge of language idioms or design esoterica, one’s bias would naturally be toward the more elegant one on a team familiar with those or invested in learning them, and toward the more workmanlike one on a team that’s optimizing on other priorities. (Interpret team under the sign of Heraclitus: the same group of people is a different team from one moment to another.)
