Hardener has never been a requirement to fix B & W Film. When emulsions were softer and the film was to be processed in a roller transport processor, hardenr was used to protect the film from scratching. When the films was dry, it was not more hard for using hardener.
Hardener does not enhance processing but restricts it because as it hardens, it restricts the flow of chemicals through the emulsion.
