There isn't an advantage with a top level 5 subvolume being used for rootfs. But if it's not being mounted, rather other named subvolumes are, then the advantage of a subvolume for snapshots is that it can be independently mounted to provide access to all snapshots within from which to create derivative snapshots. And it can also have a nosuid or noexec mount option to prevent old vulnerabilities from being root executable.
