It would be nice if the keyfile were saved (and synced between devices) on the iCloud Keychain, the way it's done on 1Password and RememBear, to name two. This would make using a keyfile completely transparent to iOS users (and allow it to be enabled by default), and it could still be synced to non-iOS devices (or other iOS devices if iCloud Keychain isn't enabled) by QR code.
