usernames cannot begin with a number

WHM's default behaviour dictates:
1)name the user after the domain
2)don't let the username start with a number
3)if a domain starts with a number, indicate success yet don't setup the account (that seems to be the procedure with any error)

.. am I the only one who's noticed?
