This is really a non-issue in practice. In the olden days, you’d just make the change and then spend a pleasant hour or two fixing the callsites by responding to compiler errors in a pretty low-thought, mechanistic way. Nowadays you can outsource that part to a coding agent and get on with your life.

In any case, the fact that the compiler knows what code needs to be updated is a real superpower.
