In that case I'd love for it to include resuming downloads though, but given the differences I don't think merging is going to be more useful than just adding the feature in curl.
Edit: nevermind, I just learned that wget can download a page's resources or even inline them (-k apparently), that's a bit of a way off from curl's purpose. Better keep them separate tools, although wget might benefit from using libcurl so they don't have to implement lots of stuff like https or http2.
