There's a lot of Men-in-Teaching advocacy, in part because its thought having male teachers tends to be beneficial for male students[1].

I think stuff like that is the main reason to be worried about gender imbalances. A 40-60 imbalance probably isn't a big deal, but once you get to like, 90-10 or worse, as is the case with early education, you start to get a bunch of secondary social problems. Kids who associate learning as a woman only thing, or the culture around engineering or software becoming "boys clubs" that become uncomfortable for the women who do want to work in those fields
