To quote (not verbatim, but in essence) what several people said on that
at the meeting:

Ron Beard: Several calls of the SRG have not resulted in any substantial
data on what a change would cost or damage.

John Seago: In many environments, even getting an answer to the question
of what it would cost to abandon UTC ~ UT1 would cost substantial
amounts of money.

William Klepczynski: In safety-critical navigation systems, leap seconds
will over time cause catastrophic system failures that will cost many
lives. This long-term risk should justify even considerable one-off
expenses to fix permanently the problem of a commonly used non-uniform
precision timescale.

[... all quotes modulo my rapidly decaying memory of course ...]
