On the one hand, deanonimization attacks are never entirely avoidable on unhardened targets and this one isn’t particularly sophisticated and leaks relatively little information.
On the other hand deanonimization attacks are always bad and it’s a good reminder to people of the risks they are taking. This is also slightly non-obvious behavior, even if it makes sense to the technically competent, as something like an IP grabber normally requires user interaction such as clicking a link. It’s also a vector that CF might be able to mitigate by patching the ability to query a given cache directly.
