You get every girl in breeding range with most in some middle ground since it will have the most broad appeal. One extreme is not very appealing to a portion of men while the other extreme isn't either.
A gacha game that goes too far into one or the other without balance never gets off the ground. You'll see this kind of thing with vtuber agency generations too where they have multiple body types to fit a niche so that the girls have less competition and/or more unique appeal within the viewers who get attached to them.
