Weren't you just complaining that *I* was overcomplicating things?
I see no evidence to justify inventing a user-visible GUC here.
We have rough consensus on both the need for and the shape of a formula,
with just minor discussion about the exact parameters to plug into it.
Punting the problem off to a GUC is not a better answer.
