having recently spent lots of time in the Dragon Age Inquisition character creator, I really really hope we get more than just face options. DA:I has lots of good face options, but there is no body customization whatsoever. Your character as a man or woman of [race x] always looks the same other than the face. It's annoying.
Do any games have it? If not, I'd go for a technical issue, if you allow body customization, it could really screw up animations, induce clipping, screw up clothing textures, lots of nasties. But if some games do it successfully without those issues, then I'm wrong
