The 'handlers' package is expected to contain more classes over time as the number of event-handling behaviors grow. By contrast, the other packages are expected to mostly stop growing once the necessary functionality is in place.

The 'event' and 'codec' packages are expected to see less mainstream usage and are therefore stowed a little further away.

The base Proton exception goes in 'proton', but more specific exception types would reside in the various subpackages above.

There are some classes we intend to deprecate or remove: Connector, Listener, Driver.
