I'm willing to accept a little bloat and pass on inventing wheels myself if I can grab something reliable off the shelf. I don't think that makes me less self reliant.
The point seemed to be that even a rock-solid tool like curl started out tiny — just a few hundred lines — before growing to cover all the edge cases you’re describing. It’s more about showing that you can start with something simple for your own needs and customize it without depending on someone else.
I try to choose wise, even if someone will later throw shade on me for not being "self reliant" or some other insult of the day. If my goal is to write a better libcurl, then that's what I'll work on. But that's basically a solved problem and working on that doesn't seem like the best use of my time.
