Right, a lot of the draft law being male-only reflects a combination of the reality that, relatively speaking, not much war has been waged since the end of WW2, and that much of contemporary gender equality is still somewhat new on a historical basis. So they're really just out of date laws with not much of an impetus to update, at least until recently. The worldwide trend is pretty clearly in the direction of making service and conscription, where needed, more gender agnostic. There are still some realities that don't really change here, such as men being most useful for direct combat, so even if women are conscripted it's likely they'll still avoid much of the worst of warfare simply by virtue of not qualifying for stringent standards.
