The issue with specifically making unisex gear and hairstyle designs is that it risks leading to most gear being designed to be either feminine or androgynous. The people who enjoy dressing up their male characters in such a manner do not mind, naturally, though those of us who want to dress our characters based around conventional male beauty standards or just 'Rule of Cool' end up being screwed over. More variety in general would be neat and as part of that variety I think it's best that gender locks remain in place for some gear so there's stuff that can specifically be designed with the male models in mind.
