The geniuses could design the ECU to employ use a super-cap. If a positive cable should touch negative during a disconnect say adios to the memory backup. A supercap could power the volatiles for how long? Regardless of cause of power failure.

Imagine what would happen with the first "super genius" back yard mechanic that accidentally shorted the battery terminals with a super cap attached to the ECU..
Even IF there was a super cap placed in the ECU, it WOULD have to be designed with at least a blocking diode to prevent heart stopping lightning and thunder from happening in case of accidental shorts..
Not everyone will want to own their own heart defibrillator in their car..
