I'm not sure IF we are ever going to remove the access class. Maybe
some other RabbitMQ dev can answer this question.

The problem there is that after a read timeout, an exception will be
thrown, breaking most consumers out there. What the library needs to
do is to handle those timeouts internally and then abide by the
timeout parameter passed to channel wait().

In the meantime your solution might work. In my case, I'll try to
implement AMQP heartbeats.
