We are not planning any major work on it in the foreseeable future.
We haven't received many bug reports or feature requests since releasing 
it. Which could mean either the plug-in works perfectly, or it doesn't 
get used much, or both :) Take your pick.

As the description of rabbitmq_tracing says... it "Adds message tracing 
to the management plugin. Logs messages from the firehose in a couple of 
formats.". So the actual tracing is done by the firehose 
(http://www.rabbitmq.com/firehose.html), and that's what 'rabbitmqctl 
trace_{on,off}' controls. Hence even without the rabbitmq_tracing 
plug-in, there is a cost to running with tracing enabled.
