If that's going to be possible, shouldn't it work for any
MTD device?  And the lack of protection bothers me a bit
more here than with EEPROMs and NVRAM, since it seems kind
of easy to clobber UBI (or JFFS2 etc) data.  Maybe there
should be a way to make jus a specific partition available
this way?

Worth a separate patch.  That much raises no flags for me.
