Good point. I seem to recall there being some discussion a few years ago around the wisdom of having to write to a file system to fsck it. That is, if you know the file system is broken and want to fsck it but you don't have a way to interactively run fsck yourself, do you _really_ want to be modifying the file system? It's entirely possible that, by writing /forcefsck to the file system, you destroy some other valuable bit of data that fsck might have been able to save.
