It makes sense. If you're going to use MTD drivers for other partitions of the flash, you want to be able to co-ordinate with it so you know when the flash is being written to. You want to be able to use its partitioning rather than hard-coding the physical address and length of what might be a dynamic partition. You want the MTD driver to know that the device in question is in use.
