@KoosPol @kbr @edwintorok @filippo There's actually already terminology that's more accessible and less confusing: "double encryption" and "double signatures" are safer than "single encryption" and "single signatures". People tend to say "hybrid is safer than non-hybrid" since that's more concise, or "ECC+PQ is safer than PQ" since the usual situation is that we're adding a PQ layer (trying to protect against quantum attacks) and keeping an existing ECC layer (to limit damage from PQ failures).
