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.

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.
