First I don't think there needs to be any rules for size or gender to effect ability scores, I am very happy that 4e did away with ability score penalties based on race.
But would an optional rule presented in the main book stating that females receive a -2 Str, but gain a +2 con,dex,wis, or cha be acceptable. To be honest the smartest person I know is my sister in-law so was very tempted to add int to the list as well. But women's pain threshold has been documented higher than mens, they usually make better ballet dancers and gymnasts, are more intuitive and almost always have better social graces so the other stat modifiers are pretty easy to see.
I then see a lot of min/max male players making female wizards, clerics, rogues, ect... So honestly I would not use the rule but wondering how the people wanting females to get a penalty feel about it.
