I've suggested at various occasions that the IERS should be the authoritative

There were discussions at both the 2013 and 2011 UTC meetings
Which meetings? I mean, what standards body?
well-aligned with what Martin says, for both leap second info as well as more
general Earth orientation data. One or the other or both are needed under all
scenarios. These are the sorts of details that should be hammered out in
advance - and it has never seemed controversial among any of the stakeholders
that reliable information should be provided in a good format using flexible
protocols implemented on scalable hardware with robust network connections.
If I understand the provenance, BIPM is responsible for maintaining
atomic time and TAI, IERS is responsible maintaining for UT1 and Leap
Seconds, and ITU is responsible for "time dissemination". Whats not so
clear, and it would be reassuring to know, is how the information is
officially shared between these bodies and to what degree its automated.
If ITU is responsible for "time dissemination" it would seem like they
should also be responsible for "time metadata dissemination", ie: Leap
Second announcements, history, and related.
