Switch button icons found in the PC version of Red Faction Guerrilla Re-Mars-tered

Here's a bit of an odd one, and we're not quite sure what it means. People have been picking through the files found in Red Faction Guerrilla Re-Mars-tered, and a rather interesting discovery was made.

The above compilation image was found, which shows off Switch Joy-Con buttons. Why on earth would this be included in the game's data? Could the game be making its way to Switch? Was the port planned at some point, and then cancelled? I guess we'll just have to cross our fingers and hope for the best!
