I was definitely on that thread, I just didn't register this as a PTP security proposal specifically.
It seems like this really would work just as well with GPS, or any GNSS, with any of the TESLA-secured modes (such as GPS Chimera and Galileo OS-NMA) instead of PTP. 
Or unsecured GNSS, or a radio clock like the DCF77 broadcast sender.
It also seems like it would work with something like Roughtime instead of NTS4NTP.

Personally, I believe this is a really important approach to follow up on.
I'm just not sure that it is worth the effort to focus on NTS+PTP specifically and market that as a security solution for PTP... but that gut feeling could definitely be off.
It just feels to me like it might be more interesting and fruitful (long-term) to make this into a generically applicable thing; I would be willing and able to contribute serious amounts of work to such an effort.

My proposal is what's described here; I believe you were on the
thread: https://mailarchive.ietf.org/arch/msg/ntp/-gQcQH915bf7NFTCjJ8LfVe8aa4/" rel="nofollow">https://mailarchive.ietf.org/arch/msg/ntp/-gQcQH915bf7NFTCjJ8LfVe8aa4/

There's no associated I-D right now. I'd be happy to turn it into one
(with Informational intended status) if the WG thinks that would be
useful. If I do, I'd like to have a coauthor (someone who's worked
with IEEE1588 more closely than I have) to write the section on how to
process PTP packets once a plausible interval has been computed.
