With the years and time that have gone by, it is really a surprise to me, that we are stilling looking and have not found the recipes to Fg7, Harvey 777, Hygrain, and a host of other developers and other formulas..., that are 30 or more years old.
Formulas cannot be patented therefore manufacturers hold them as trade secrets. Rodinal is over 100 years old and the exact formula remains a secret. For most people this is not a problem as they realize that an inventor has the right to the profits of his invention. Sorry but this is how the free market works. There are plenty of developer formulas that are in the public domain of many types; one-shot, fine grain, .... It is not like you are being deprived of the ability to develop film. There is no "holy grail" of developers and one would be hard pressed to identify the developer used when presented with only prints. In the end it is the photo that matters and not the method of attaining it.

A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral.
