I can't see the point in having this feature unless the extension is being used on Flux. I was thinking yesterday, why not just make it a version check thing. If it see's Flux, then display the "Currently used extensions" thing, if version ='s pun, then leave it blank.
Pun is already being promoted if the version check ='s pun anyway.
If it bothers anyone that much, then you could probably edit the manifest.xml for the extension and remove anything that looks like this. I am not sure if it will screw anything up, I haven't tried.
