Question about SRTL_OPTIONS parameter

Dear all,

Does SRTL_OPTIONS parameter work on Rover?
The documentation says that this parameter decides whether ignoring pilot yaw or not during SRTL flight mode (https://ardupilot.org/rover/docs/parameters.html#srtl-options-smartrtl-options). However, Rover always ignores the pilot’s yaw regardless of the parameter.
Thanks!
