I don't think this will ever happen purely based on people purposely building accounts specifically to achieve the untrimmed variants of these capes.
I mean, I understand the limitations set and know full well they're by choice of the individual but wouldn't it be safe to say this is ever so slightly unfair to the people that have dedicated up to 100s, or maybe even 1000's to do this?
Besides, what benefits would this have other than allowing people to alter their outfits slightly?
On the other hand, I'd love my untrimmed Crafting cape back. Was a beautiful cape to own.
