Some steam games might still have the steampi and steamworks dll’s, so that’s still 2 bits that need to be deleted before they’re effectively identical.
Having the installers can be important, not every game may work out of the box if you only copy the installed folder to a different machine, some important configurations that are set up in different folders, like in %appdata%, might be missing. Steam checks if DirectX and the proper MSVC versions are installed, I suppose the GOG installers do that as well.
