I understand. Regardless, when both parties are serving, one must account for longer maternity leave on account of lack of physical fitness, as well as time needed to raise a child, even with robust childcare systems. From a career perspective, this is undesireable.

I'm unconviced this is sufficient reason. Semblances are based on personality, though, and there are no guarantees, even accounting for the semi-hereditable nature. Consider personality archetypes and how those play into the limited number of possible superpowers. Even if there is pedagogical preference, I don't think that's enough.
