I had `firstHeaderName` at first, but I didn't like how that name doesn't signal what the purpose of the field is, and the type `String` doesn't tell us much either. So, I switched it to `runtimeHelperName` (there might be a better name). If we ever decide to change the location of the helper methods again, the name would still work, since the purpose stays the same.
