I would like there to be a way to change account user names mainly because I have recently found out that I've spelled the name I wanted wrong thx
Make a new key with the name spelled correctly.
How is this a bug?
It should be in the BYOND feature request forum.
And even there, if you use the forum search, you'll come across reasons why this is not feasible.

Your best bet is to go with the suggested creation of a new key.
Keep your name and claim it's "metal" upon criticism.
