I hate how much the NSA will sing the "I told you so" song, due to utter chaos caused by composite classic/PQC algorithms.
@sophieschmieg due to people getting the combinations wrong or....?
@erincandescent no, due to things getting bogged down in discussions, combinatory explosions, and technical complexities, while the pure algorithms are making steady progress.
At this point in time, it's likely that many scenarios will deploy pure PQC versions simply due to combiners not being ready yet, and not having a clear timeline to be ready in the nearish future.

Do you mean for encryption, signing, key exchange, or some subset?
@robryk @erincandescent all of the above, but especially signing, since encryption might just go with X-Wing.
