 I think the point is that it goes to disk to allow out-of-band restoration
 in case writing back with flashrom fails?

 I would prefer no file. I don't want to have to remove files after
 testing, and not having a file would encourage testing strictly with flash
 chips without valuable contents. I think that is a very good thing™!

 There's always -r to do a manual backup first, but I like the idea of
 making the difficult path more labor intense, to discourage testing with
 critical flash chips.

 > 3. write (old contents)
 I think it has to write all 0 to the chip rather than the original
 contents. If the chip is blank to begin with there would be a false
 positive when erase or write does not work, and flashrom can't tell.
