When adding a sysext image to the system and manuall merging it, a later "systemctl (re)start systemd-sysext" won't work because "merge" refuses to work when something is merged already. Another problem with "merge" at start plus "unmerge" at stop is that a service restart can't make use of the new MOVE_MOUNT_BENEATH in the future even which would only be available in "refresh". It also prepares us for setting up the merged overlay for the sysroot from the initrd already, which also would lead to the mentioned start problem of the service (One optimization could be to skip the loading but only if we are sure that all images were loaded and weren't modified since - this assumption is hard because early services could want to inject a sysext, too). Use "refresh" on service start to fix the problem that the service can't start as soon as a manual merge was done. Also add a reload action that allows to issue "systemctl reload systemd-sysext" and it will make use of MOVE_MOUNT_BENEATH once we implement this in systemd-sysext refresh (and it's available from the kernel).
