How about opt-out for reading (which is non-destructive) before writing/erasing and opt-in for automatic restore?
There are some heuristics and techniques you could do. Read it in initially makes sense. But create a file in all cases? What if they are on a readonly file system when running flashrom (which I do frequently)?
But if it is unchanged after an erase, then further action may be bad. I have had cases where the flash "seemed" to fail, but the flash part was fine. Trying to restore it might make it worse if the cause is a timing or MTRR issue. I've seen that too.
Automatic recovery is very tricky in these cases.
as for traffic such as this, I think leaving it on coreboot is fine. We are not a heavy traffic list at present.
