I'm slow at gaining pantheon points, so just recently I uncover that I kinda wasted my point on titan body mod for giants, as it only affects male giants. I wished to modify my female giant ruler only to see that I do not have that option. Right now this option is just copy of unit body type. I would not mind if there was just slight modification to it, or even none, just to have it on both genders.

This has come up a bunch of times. You are 100% correct. It should be there. But the developers only made male titans, so it was easier to just port those assets into the pantheon.
