So when I compare them to something I know will last more than a decade before inexpensive maintenance like Campy Chorus and Record, even Super Record the value proposition is weak for electronic drivetrains. Campy Record slots in between them cost-wise, while Super Record is a few hundred more than SRAM.

Not convinced it is a good way to go.
