What happened to these options...and can we have them back?

This is from one of the April Fools backer updates;


Now, the cryptocurrency mining options were a joke. I get that. Can we talk about what's up above them, though? Those are display toggles for the Headgear, Accessory, and Scarf slots. I have no idea if this was a mock-up or actually existed in the game at one time in development, but this does show that - at least at one time - including toggles for cosmetic visibility was considered. Maybe it was even planned to happen. It didn't make it into the final version, though, and now exactly this functionality is something that I frequently see as a requested feature.

What happened here?

Is it possible to get these options in the release build of the game?

Anyway, posting this to Suggestions because it is a highly requested feature, and I think this makes a strong case for it being added (as it possibly almost was).
