As of my last knowledge update in January 2022, Historic Formula Ford 2000 doesn't represent a widely recognized or standardized category in historic racing. However, it's possible that new events or series have emerged since then. In the context of historic racing, Formula Ford typically refers to the 1600cc class, which has been historically significant as a stepping stone for young drivers. If there have been developments in the motorsport landscape, particularly with the introduction of a Historic Formula Ford 2000 category, I recommend checking with official motorsport organizations, event organizers, or dedicated historic racing communities for the most up-to-date and accurate information. They would be the best sources to provide details on any recent or niche developments in the world of historic motorsport.
