With Deno.serveHttp marked as deprecated is there a way to run an HTTP server off of a Deno.Conn?

const server = Deno.listen({
  hostname: "0.0.0.0",
  port: 0,
});
const conn = await server.accept();
(async () => {
  // Reject all additional connections.
  for await (const conn of server) {
    conn.close();
  }
})();
const httpConn = Deno.serveHttp(conn);
for await (const requestEvent of httpConn) {
// etc...
