Hi Uri,

You consider pure-PQ risks – then don't usee it. I consider risks associated with hybrids, so my deployment will not use them. To each his own.

According to a draft authored by Reddy and Tschofenig, "Pure PQC Key Exchange may be required for specific deployments with regulatory or compliance mandates". The authors then go on to list "high-security environments" as an example of where Pure PQC Key Exchange is required. An assessment of risks would be different in such environments.

The web browser vendors decide which algorithm(s) to deploy at my location. That's usually how it works for everyday use. I doubt that the everyday user would be asking for compliance with the (U.S.) FIPS 203 standard (please see Section 1.1 of draft-connolly-tls-mlkem-key-agreement-05); It's unlikely that the user would have heard of "FIPS". It could be different in other parts of the world.

Don't try to stuff your perception of risks and correctness into everybody else's throat.

The above sentence seems a bit strong.

Regards,
S. Moonesamy
