Definite no from me. I find the lack of gender roles incredibly refreshing, and besides, gender roles would remind me of how, because of my religion, I feel personably culpable for everything bad in the world. I play this game to distract myself from that little problem.
Honestly, if it became a feature, I'd probably stop playing.
It should never become a feature for dwarves, because they are gender equal. It is one of their "ethics" which they actually follow.
Among humans, though, males are stronger and generally dominate is a way which is not, and never should be true for dwarves. For humans, though, there should be some kind of gender roles system in place, though remember that in reality a female metalsmith would not have been astounding because wives often helped in their husbands' businesses. Armies should be male dominated unless they are defending settlements against overwhelming odds or the civilisation is so martial that everyone learns to fight (the ancient Scythians were like this, and women also learned horse archery and fought to defend camps from the enemy, hence the Amazon stories. One Scythian queen, Tomyris, led her army to defeat King Cyrus the Great of Persia and kill him.) Nonetheless, men should dominate most human societies. Animal torture should also be common.
If you do not want to play with gender roles, stick to playing dwarves, who should not have them.
