Isn't all this post quantum stuff a little premature? The standards haven't settled. We don't even know if there is a possible quantum threat to cryptography yet. The more we work on the problem the less likely it seems. Last I heard we were 1 or 2 orders of magnitude away from physical noise performance that would make such a threat possible.
Edit, added: Harvest now, decrypt later applies to any encrypted data. There is nothing special about the quantum threat. This all only makes sense if we can predict what the actual threat is ... and so far we can't. This reminds me of Pascal's Wager[1]
