Minimum username length of 8 characters is too restrictive

[miminashi]

I think the minimum length requirement of 8 characters for usernames (AccessKey) is too restrictive.
It prevents using common names like "root" or "admin".
Is there a specific reason why a minimum of 8 characters is required?

This is the validation.
