Why do so many B&W film developers contain so much sulfite? Is it because, historically, devs like D-76 (with 100g/Liter) were used in replenished deep tanks?
Sulfite is a preservative and mild solvent which gives better image quality.

Make one up and test it. Seeing the results might explain it better.

and the sulfite to as little as 75 g/liter with good results
but, I want it to be less expensive still.
