I have a third use case for replace: 3. Simultaneously developing a library and client for that library. For example, if I have a library to access a network service or piece of hardware and want to extend its API, I find that working on the client along with the library helps me iterate to a good API. I use replace to get that to work. But I think that newcomers to the language are unlikely to run into that case either.
