As much as I think that's correct a lot of the time, something like Bruno has value too. Implementing complicated auth for an annoying service once and reusing it across several pre-written requests, useful features like a GUI and history to see prior responses from an endpoint, being able to share the "collection" in the repo as examples/developer tools that's maintained alongside the code, writing docs with each request to explain its usage, this stuff does add value that isn't trivial to do with curl.
