I think that is a good idea for the game, because we are in the future so I think that the game need to have a option to we change the appearance of V.
I did find it unusual that you couldn't do a appearance change later in the game (change your face or eye color). Considering that this setting has so much emphasis on how easily it is to change your body.
I expect this'll be added. I don't know why but it seems fairly common for this feature to be added later (Skyrim, DAI and the additional hair styles in Witcher 3 spring to mind)
