This name is hard to parse (long and a bit confusing). Could a simpler name suffice (even if less precise)? E..g `insertIfSecondaryFunctionParam`? or even better just `insertIfSecondaryParam`? The reader will have to look at the function definition comments to understand the name, but I think that will be necessary regardless.
