I hate the rewrite treadmill. I'm dealing with this now. One of the APIs we use is migrating to a different API. Of course they completely changed the data structure. So now we have to rewrite entire components (they don't want a service layer to restructure the data), there's nobody left from the original team that wrote it, and the only requirements we have are "make it work like it did with the old API". Surprise surprise, we have a lot of bugs showing up in prod.

This is how you burnout people - have people do boring yet frustrating work, make them do it the hard way, then put them on a deadline with other competing priorities.
