We don't want to rename devices in the kernel namespace anymore. There are races with name swaps which are impossible to fix. If people want persistent names, they will need to configure the devices to have such names, and these names will _not_ be the kernel names. When we'll get there and can provide a tool to or the mechanics for a possible tool to do that, all the rule_generator stuff will go away, hence we did not integrate any of the rule-copy--over-to-the-rw-rootfs in systemd, and we don't plan to. Same for the cdrom rules, if people need static names here, they will need to configure them. Allocating a new number in this rules file in /etc for every USB-G3-modem with a fake-cdrom is really nothing we want to continue too. So that will go away in the longer run too, and require explicit configuration with some to-be-find-out-how-it-will-look-like system management tool integration.
