I've done what you have asked of me https://review.coreboot.org/c/flashrom/+/69131

Although this change was extensively tested as well as has a breakdown into its constituents (abandon patches) from which it was squashed together.

Personally I feel there is more opportunity to introduce bugs messing around between representations between commits even though your idea in principle is good. In any case I have done what you have asked in CB:69131
