Mixed-Case Usernames

Disclaimer: This may not be important enough for many FC users. But I'm just checking the possibility. I mean, if it's easy to implement for the FC team without any consequences.
Currently, all usernames appear in lowercase. However, I'd love to see them mixed-case, like it's on X (Twitter). TIA! 💚✨

Example: @mixedcaseusername vs @MixedCaseUsername

[It just looks visually appealing.]
