What is the purpose of Rails::Initializer#add_support_load_paths ?

Hi there,
i was just hitting random pages on the api pages and i started reading
the documentation for the initializer when i came through this
completely empty method. I check at the code (initializer.rb) but
didn't find anything *hidden* to justify it's presence...

Any clues?

P.S.: The reason i'm asking is 100% pure curiosity :slight_smile:
