I was going to submit a plugin I've seen hundreds if not more requests for. The plugin took 5 minutes. Your submission process takes nearly an hour, and doesn't even guarantee acceptance and that I'm not wasting my time. I'd quite frankly be embarrassed of the state of things over there if that was my part of the site to run.
Takes less time to submit a Google Play or iPhone app to the app stores. No wonder the plugin directory is dying off and is full of plugins that don't work.
