If an EAHRS system fails in flight, fallback to EKF3 would be desireable. Currently, plane can fall back to DCM, but copter has no fallback. An EAHRS failure on copter can have disastrous consequences.
Describe the solution you'd like
If configured, EAHRS failure with EKF2 or EKF3 active and working would fall back to EKF. This would make the vehicle more robust to an EAHRS failure.
