why sc-lio-sam and mulran player support different gps message types?

[JaySlamer]

Thank you for your fabulous work. I am trying to use lt-mapper to merge two maps hence using SC-LIO-SAM to generate individual maps. In the process I notice that the GPS publisher in mulran player is of navsatfix type while GPS subscriber in SC-LIO-SAM odometry type, which result in that the later can not use information published by the former.
Is this done deliberately?

Very interesting question, which I have also asked myself.
