I suspect that's one of those cultural mores.
I heard it described as a "domestic engineer" once.....and I thought,
"But it's G....who fixes the hoover and the washing machine "

LOL. I've heard that term too. But not for a spouse; rather that's the term for a paid housekeeper/maid.
"Home-maker" is a term that gives deference to a good wife who makes an ordinary "house" a true "home."
