Let me put caps in username and Change username on legacy badge

I wasn't aware we were gonna get our current name as badge on profile. I had one that was a nickname themed around my profile theme at the time and would like to change it to what my actual username would have been. also not allowing caps prevents me from actually using the username I want and something that just bothers me on my profile. I believe discord should allow the legcay badge username to be changed if available in cases this happend like maybe one time atleast, as well as allow caps in username for people to actually be allowed to use their actually username which may have caps involved like mine. Honestly though they should have just kept discord the way it was no one asked for usernames.
