Maybe, but panopticlick is still able to fingerprint me to the point where I'm unique.... over 17 bits of identity in my browser (means you can identify me in a pool of up to 2^17th people).
Try it yourself.

Hopefully we can try and vastly reduce the leakage from navigator.plugins, but that might be hard to do without breaking the web, sadly.
In my case, for example, it says that roughly 1 in 6 browsers (of those tested by them, I suppose) have JS disabled as I do, so I don't stand out too much. However, my user agent string is 1 out of 100 and HTTP accept headers are unique among all 140k browsers they tested, apparently due to the unusual language preference settings I once made.
