In the 7 year interval where no leap second was required/scheduled I heard several people saying we might have needed a negative leap second.
Fortunately, this is not a matter of speculation. An easy way to see the trend of UT1 - UTC is to look at DUT1 (published in Bulletin D). DUT1 is an approximation to UT1 - UTC and has always stepped down (except, of course, at positive leap seconds), ever since the earliest Bulletin D available on the web (1991-06-20). Before a negative leap seconds would be scheduled, we would see DUT1 stepping up several times in a row, so there _is_ some advance warning.
