Well, I'm not sure if it is appropriate to attribute this behavior to Unity. According to the blog entry posted above:

Some years ago the Plasma hackers started to address these issues by implementing a new specification called Status Notifier. This specification got also adopted in Unity/Ubuntu as the Application Indicator.

The only thing that still bugs me is the fuzzy icon issue, but it hopefully will be corrected soon. In any event, you've got the legacy method still available for about another year; but it probably will stop working in Fedora 22.
