While I think the original ubiblk that was read-only made sense to allow the usage of read-only filesystems like squashfs, I am not sure a read/write ubiblock is useful. Using a standard block read/write filesystem on top of ubiblock is going to cause damage to your flash. Even though UBI does wear-leveling, your standard block read/write filesystem will think it has 512 bytes block below him, and will do a crazy number of writes to small blocks. Even though you have a one LEB cache, it is going to be defeated quite strongly by the small random I/O of the read/write filesystem. I am not sure letting people use read/write block filesystems on top of flashes, even through UBI, is a good idea.
