Why wait? An advantage with creating TI is that it need have no connection to UTC at all. Stand up TI separately and immediately, and deprecate UTC (or don't) when convenient.

Or Markus Kuhn already pointed out that they could just recommend TAI. This would be similar to the Pluto debate at the IAU - the working group suggested one solution and the assembly adopted something completely different: "You need a timescale without leap seconds? Hey! You already have a timescale without leap seconds."

Presumably the documents already correctly describe the connection between TAI and UTC. Recall that the notion appears to be to later deep-six TAI. The precise effect on documentation is as unplanned as every other aspect of this proposal.

The right thing would also have included publishing proceedings for the Torino meeting.
