Publish can fail silently

RobotWebTools/rosbridge_suite#414 (comment).

My Goal is to know with ROSLIB whether a topic is published or not.
I had a look at Service.js and Topic.js, especially the callService and publish function.

callService uses callback and failedCallback while publish only uses an object. Would there be a way to modify the publish (and other script if needed) to solve the problem ?
