Alternatively, it could be used a state of charge tracking mechanism that conceals battery degradation. Say the battery has 100KWh, but the remaining energy gauge reads zero after 80KWh are expended. You could be degraded to 90KWh but you wouldn't perceive any reduced usable energy until it degrades below 80KWh.

This seems contrived - the whole point of incomplete charge / discharge cycle is to spare the battery from degradation.

Yes, and my point is that the mechanisms to prevent battery degradation can often end up masking the degradation. This isn't nefarious, it's the byproduct of good state if charge management.
