Maybe a third-party system would be suitable? I feel that voting systems are not just for the dev team but for the community too, to see where their own ideas stand against others.
TheWyrm I think Tom is busy on making the new arcade which will have support for 3rd-party plugins.
Also, +1 for a disabling plugins feature, had an issue recently where a plugin that I required for exporting was preventing preview in browser from working, meaning I'd have to build (XDK) every iteration to test on device...
Thankfully, it's been fixed now but for things like the previously mentioned FGL, it'd be a big help in cross-platform exporting as you only need one project instead of 2.
