For now I've only used blockdev-reopen for turning backing files
read-write and back for bitmap manipulation. In such case I presume it
doesn't really make sense to use the batching if I ever need to reopen
multiple images.
Other than that, the blockdev-reopen code is still dormant in libvirt so
it's easy to add the extra required wrapping without any problem.
