The return type doesn't have to be a Pydantic model, it could be a different type, like a list of integers, or a dict, etc.

### When to use `response_model` instead

     * @param options The options to use for serialization, may be {@code null} to use the default values.
     * @param toolchains The toolchains to serialize, must not be {@code null}.
     * @throws IOException If the toolchains could not be serialized.

 *  Fix: Don't crash if a TLS tunnel's response body is truncated.
 *  Fix: Don't track unusable routes beyond their usefulness. We had a bug where we could track
    certain bad routes indefinitely; now we only track the ones that could be necessary.
 *  Fix: Defer proxy selection until a proxy is required. This saves calls to `ProxySelector` on
    calls that use a pooled connection.


## Version 4.3.1

 * the beginning, thanks to using different `-source -target` values for compiling our `-jre` and
 * `-android` "flavors.")
 *
 * (We could consider releasing a listenablefuture:1.0.1 someday. But we would want to look into how
 * that affects users, especially users of the Android Gradle Plugin, since the plugin developers
 * put in a special hack for us: https://issuetracker.google.com/issues/131431257)
