Well, it's specifically not marked as supported on the PluginIndex page, and I don't believe it's in the Nano's manual either, so I think it's fairly clear that it's not supported on Nano yet in applicable documentation. If you'd read it, you'd have saved a few days of problems.
As for work on it, the core devs are working on more important things, and nobody's really stepped forward to fix the scaling code that would need to be adjusted.
