Simple, because there has been no work involved.
Only thing they did was renew the license/contracts with the GARO guys, and then just copy, paste.
Remove genderlock is actually involving a lot of manpower, & resources you're asking a lot from this indie company.

Sarcasm aside, personally I'm more a fan of 'uniqueness', but I do know it's 2022 and the majority in the world wants everything to be the same so...
Maybe they will change it but I wouldn't put my hopes up too much.

As the guy above me posted I'd like more work involved in the content itself as well but I also know that the people working on the clothes are not the same as quest designers, battle content designers, etc so there's that.
