The issue with women having more than one partner is that there is more than one possible father. If a man is with more than one woman then mother is not in doubt. If father is not known then that creates responsibility deficit. You need men like Pandav - extremely responsible men who won't differentiate between their own/bio child and another husband's child. Even then they had rules that ensured clear paternity. More likely if more than one man maybe responsible for a child then nobody ends up taking responsibility for the child.
See with Niyog a woman had multiple partners (i.e. Kunti), but only one "father" = Pandu. Or you need circumstance like Pandav where all the men were responsible and cooperative for the multiple men & one woman situation to workout.
