Does it matter if the `encrypt` mkinitcpio hook is included on a system without full disk encryption?

Can I share an /etc/mkinitcpio.conf between two Arch Linux systems, where one requires the encrypt hook for LUKS disk encryption, and the other does not? i.e. will it cause a problem booting the latter when the hook is called and there's nothing to decrypt, no /dev/mapper/luksdev in fstab? (I gather cryptsetup must be installed, but that's fine, and it actually already is as a dependency of something else anyway.)
