Yeah, I mean, converting ENF to DNF is "conceptually easy", and "doing it yourself" by writing some code to do it is surely easier/faster than finding and reading about and trying to understand some package that does it for you!? That's the time trade-off: do it yourself, vs use external package. --linas
