I completely agree, but so much discussions about NTP today are built upon the POSIX definitions. For example by having Google (and possibly others) having NTP servers that do smear.

<https://developers.google.com/time/smear>

Personally, I find the fact the leap second itself is undefined is of no problem for NTP or implementations. The problem is when the implementations have to push the response from NTP into a POSIX based environment that do not take leap seconds into account.
