Additional context
The current rule does not account for the various Tangent types that can be seen when working with downstream packages (specifically note AD'ing through observable functions via SII). It is much better to remove the rule and let AD take care of picking out the right fields etc. If its preferred to retain the rule (to get the VectorOfArray type returned in the reverse pass), then we will need to handle that elsewhere. For now, let's check for breakages in CI.
