Interesting!
I'm curious now what's the process or how to request to change your username.
Is there any factor to consider?
Everyone has a reason for a name change.... yeah
Yeah, if that's for security reasons, we need to respect them and IMO, if my username changed, I don't want to disclose who I am in the past.

Because it's useless changing your name if everyone knows who you are, not unless you want to change your username for the brand name of your company.
