I see your point about backports being more painful when you have a bunch of unrelated changes mixed in, but I would still prefer if we converted everything at once and at the same time introduced a suitable syntax-check rule preventing more instances of whatever function we just removed all callers of from creeping back in, or actually just dropping the function altogether. Doing the conversion incrementally will IMHO result in dragging it for much longer, causing more pain in the long run than ripping the bandaid would.
