Wouldn't users navigating to .onion sites within TOR be free from a GPA (global passive adversary)?
Couldn't the TOR protocol model Perfect Dark?[1] Which uses a Mix Network.[2]

2) Perfect Dark is not a general purpose net, but rather a file distribution mechanism, for known hashes. Not for message exchange between peers like tor or i2p.
Tor is a mix network aswell. But a low latency mix. The adversary is a way stronger than assumed, it does not seem to be safe anymore. High latency mixes (like remailers) are unaffected.
Also, Perfect Dark is 1) broken 2) closed source, so not trustworthy to begin with.
