Are you using it for rw mounts and if so, then what kind or write volume and sizes do you handle? Usually when this comes up, folks are using null ro mounts and the rare (and sometime unintentional) rw mounts do little or no writing. If anyone is doing significant volume or size writes, then I've not heared mention of it. Look through the sys/fs/nullfs cvsweb pages[1] to see what few changes have happened in the filesystem code in recent times. There are a few specific code changes (ie. not cleanup or restructuring), but I can't tell just from looking how significant they are.
