IMHO a better example is: "Can we make a teeny tiny change to CURL that would allow me to use it as a fetch engine for the GUI web browser I'm making? I can't think of anything else that might use that change, but pretty pretty please?"

This could have been a good example, except curl is not only a CLI, it builds on top of libcurl, one of the most popular libraries for doing HTTP in C. If building a web browser, it’s one of the first candidates for a fetch engine I would reach for.
