alt Hacker NewsIf your point is "reference implementations have never been sufficient for real-world implementations", I agree, strongly, but of course that cuts painfully across several of Bernstein's own arguments about the importance of issues in PQ reference implementations.
Part of this, though, is that it's also kind of an incoherent standard to hold reference implementations to. Science proceeds long after the standard is written! The best/safest possible implementation is bound to change.
I don't think it's incoherent. On one extreme you have web standards, where it's now commonplace to not finalize standards until they're implemented in multiple major browser engines. Some web-adjacent IETF standards also work like this (WebTransport over HTTP3 is one I've been implementing recently).
I'm not saying cryptography should necessarily work this way, but it's not an unworkable policy to have multiple projects implement a draft before settling on a standard.
