I have never consciously wrapped Axios or fetch, but a cursory search suggests that there was a time when it was impossible for either to force TLS1.3. It's easy to imagine alternate implementations exist for frivolous reasons, but sometimes there are hard security or performance requirements that force you into them.

AI was trained on Axios wrappers, so it's just going to be wrappers all the way down. Look inside any company "API Client" and it's just a branded wrapper around Axios.
