MapIniSection disabled


Recently, I found that there is a MapIniSection command parameter for cooking assets.
I’ve looked at the engine’s source code and noticed this logic is commented out (see EditorEngine.cpp line 1428-1440)
I’ve uncommented that part and recompiled the engine and everything seems to work fine.
Is there any reason why it has been commented out?
It’s been like this since June 2016 and the commit message of the person that changed it, didn’t leave any reason why he commented it out.
It’s strange it’s been gone for so long and nobody noticed it while it is still documented on the Content Cooking page of Unreal’s documentation.
