Well for example if you've ever played "Four Elements Trainer" a game based off of Avatar and also one of thee most popular games on this site, the option for the players to adjust to a desired breast size was added later as a concept after a fan suggested it to the creator, originally they had one size for breasts (which was whatever the artist dictated). So, unlikely? Yes, but if something has happened before in the past it can always happen again. If no one had ever made the request it may have never happened.
you still compare apples with banana I am afraid...
Four Elements Trainer is the main project of a Patreon founded Group, while this game is a side project of a single developer+artist.
The content so far and some coments of the creator also indicate that the game will overall be rather small/short.
you would go better to compare this to the mental father "A Zombie's Life" the creator thought of adding some new outfits to the characters in game but discarded the idea later on again.
Also there are some limitations to the engine used for the project.
Four Elements Trainer is in Renpy which might allow such a "feature" but this is RPGM... as far as I remember there is no complex crafting system in Four Elements Trainer which is a limitation for that engine and so on
