I do agree. A complete solution is designing a new generation/revision of time protocol with accountability and anti-misuse as parts of its design, just like how people are implementing ASLR and NX in C programs and starting to use memory-safe languages. Or just see how TLSv1.3 removed all unsafe algorithms, so it will be little damage even under the worse case scenario.

Also, I think NTP needs more publicity. We need people to be aware of it before we could get feedback. The community then can have a watchdog team that spots misuses and publishes alerts.
