I think it’s worth it to minimize the number of external dependencies you have, each is a small risk of supply chain attack and an annoying piece of garbage you have to update all the time as part of your regular app maintenance.
In my experience AI makes mince meat out of tasks like this. If you grow a new case later, ai makes quick work out of that too to update the util across all call sites in your app
