Well, the fact is I maintain about 5-7 bottles for contrast control, ranging from as little as no potassium dichromate added to the developer to as much as 16-24 ml of a 4% potassium dichromate per liter of developer. It is really not so tedious as all, you just need to have space for the bottles, and the developer lasts indefinitely.
