Well, I'd say you left out all the important bits, to the point where your comment could easily be read as "it's the symmetric key that matters, even with public key".

But whatever. Now I know. Both the choice of symmetric key length AND the choice of public key algorithms independent of each other make this format not PQ.

Why anyone in their right mind would migrate to such algorithms in 2025 I have no idea, and especially coming from someone like Filippo it's baffling.

Those already on PQ are better off staying. Those who are not should move to a PQ, not this.
