arch default user doc clarification (or removal?)

I was trying to understand what may have been meant by The default user is arch. on https://gitlab.archlinux.org/archlinux/arch-boxes#cloud-image

There (obviously, hopefully) is no default password for that user. So how would one ever use it?

vagrant init archlinux/archlinux; vagrant up; vagrant ssh uses a user named vagrant anyway.

cloud-init will also just create new user accounts, e.g. as specified in cloud-init.

I also don't see which script in this repo creates that user.

Should that line just be removed from the README?
