It would be very useful for a re-imaging system on a shared-hosting host, with numerous jails. You could write scripts to have an end-userrestore a jail back to its original state through this mount. In this case, the filesystem wouldn't be terribly useful, except when re-imaging, so unmounting all mounts isn't that big of a deal. I do agree that it would be nice to be able to have one RW mount and a ton of RO mounts. I would even be willing to settle for having to mount the RW mount first and have this operating fail if the filesystem is already mounted RO somewhere.
