If you're building an application that depends heavily on networking for either its performance or reliability, then yes, you are better off rewriting those components and taking on ownership of hardening them to satisfy your requirements than you are relying on someone else that doesn't know your use case and has no incentive to making it work well making sure it works well for you.

HTTP is fairly trivial as well; if you're afraid of little things like that, you'll never deliver best-in-class software.
