It’s a good point that traits may not be useful now but could be useful later. Perhaps I just lack
Imagination but I can’t visualize the change of season that’s going to make micropenis a survival advantage.
Sometimes it’s not the thing that gives an advantage, but the thing it’s connected to. Perhaps the same same gene that gives them a micropenis also makes them really fit in some other area. It’s unlikely, but possible that the genetic mutation makes them immune to some devastating disease in the future. Genetics are complex.
Evolution still doesn’t work that way. If it prevents you from reproducing (like this probably would), it will be selected against, meaning it will be extremely rare (like this is), but it will never just go away unless it isn’t compatible with life (eg, missing an X chromosome).

It could be useful in a cold climate
