and saved anew but the actual function is not invoked.
Instead, deferred functions are invoked immediately before
the surrounding function returns, in the reverse order
they were deferred. That is, if the surrounding function
returns through an explicit <a href="#Return_statements">return statement</a>,
deferred functions are executed <i>after</i> any result parameters are set

It very intentionally does not offer L7 (HTTP) functionality, for instance, which would likely violate some of the goals above, without contributing to them.
Instead, the rich functionality that service mesh is traditionally associated with is deferred to the waypoints.
The ztunnel is primarily a mechanism to get traffic to the waypoints, securely.

 *  Fix: Don't interpret trailers as headers after an HTTP/100 response. This was a bug only when
    the HTTP response body itself is empty.
 *  Fix: Don't crash when a fast fallback call has both a deferred connection and a held connection.
 *  Fix: `OkHttpClient` no longer implements `Cloneable`. It never should have; the class is
    immutable. This is left over from OkHttp 2.x (!) when that class was mutable. We're using the
