they have 2 options: 1. adopt hybrid/dual encryption. This is safe against a break of the PQC layer which seems entirely plausible given that the algorithms are young, the implementations are younger, and there has been significant weakening of the algorithms in the past decade. 2. Adopt PQC without a backup layer. This approach is ~5% faster (PQC algorithms are pretty slow), with the cost of breaking encryption for everyone on the internet if any flaw in the PQC algorithms or implementations is found.
