I feel like I'm missing something. As said before, all but 3 lines are identical in these two functions.
Now you created a helper for 1/3 of those identical lines but left the other 2/3 being duplicated. Could
you elaborate why?

Yeah,.. the API is broken. Let's keep it as is. Apologies to have brought it up.
