It's very dangerous proposal when we start considering everything 0
value which isn't value to ourselves currently. Is ICMP TS known
attack vector? It has one particularly useful diagnostic purpose, you
can use it to measure unidirectional latencies up-to 1ms accuracy. It
has on occasions reduced needed troubleshooting time and reduced
amount of people who need to look into the problem.
