They are definitely of interest, and reducing e2fsck time is a very important area of development these days. We have already implemented the IRON FS journal checksumming feature, and this will go into ext4 shortly. There is lots of work needed in order to implement checksumming for the rest of the filesystem, so if you are interested to work on this please let us know.
