... but instead use a private alternative that points to the "driving transfer" from the connection. We set the "user data" associated with the connection to be the connectdata struct, but when we drive transfers the code still needs to know the pointer to the transfer. We can change the user data to become the Curl_easy handle, but with older nghttp2 version we cannot dynamically update that pointer properly when different transfers are used over the same connection.
