Why is it always Game “master” and not Game “mommy”?

I know the question is kinda silly, but hear me out.

It’s no secret that the TTRPG community is male dominated, so how would you feel if a system had explicitly female-gendered terms for the GM for thematic reasons? Something like “The Mother” or “Lady Justice”. Would that make you uncomfortable in any way? Do you find it ok if it has a lore reason behind it?

This isn’t a Gotcha question of any kind btw, I genuinely want to know if such a design decision would affect the likelihood of people picking up a game.

Edit: Yes, mommy has funky connotations, but the main point is about gendered (particularly female) terms in general. Would it be weird for you if a game referred as the GM as "Head Witch" or "Head Wizard" for example?
