See https://www.mail-archive.com/grub-devel@gnu.org/msg34346.html for the proposal of it for grub-mkrescue. This will allow GRUB to search for the volume containing the file instead of hardcoding the ISO volume label or another file system or partition attribute in GRUB configuration.

This allows to prepare an UEFI bootable installation medium by simply copying the directory structure without having to touch `grub.cfg`.

This requires mkinitcpio-archiso v68.
