Basically we used to "fake" the mount state with a file in /etc/mtab. This is now a symlink to /proc/mounts which, IMO is much safer. This is why the "mount" output has gotten bigger. As for rootfs staying mounted, I believe this is in some way due to the ability to re-enter the initrd on shutdown/reboot. This allows for nice things such as unmounting / and shutting down lvm properly before poweroff/reboot which was not possible before. So IMO this is an improvement, albeit I agree it's a bit ugly. If it's not that, then it's maybe to do with the /dev mount which must be preserved between initrd and proper / in order to transfer important udev metadata.
