Muflone [1] filed a deletion request for archlinux-iso [2]:

This package doesn't offer any use. It simply downloads the latest iso from a mirror and copy it somewhere in the system.

(since these are similar, this is a copy/paste from a reply to the tails-iso deletion request)

Before I created these I had looked for other examples.

First there's a package in community for the virtualbox guest iso:

https://www.archlinux.org/packages/community/any/virtualbox-guest-iso/

Additionally, despite the description, this package also just downloads and iso and installs it into a directory:

https://aur.archlinux.org/packages/grml-iso/

So I'd imagine that having an up-to-date iso in a known location would be useful to at least a few people other than myself, which meets the criteria of "usefulness" in the AUR guidelines:

"If more than a few people would find this package useful, it is appropriate for submission." ( https://wiki.archlinux.org/index.php/Arch_User_Repository#Rules_of_submissio... )
