I think this is a previously undiscussed option. When +/- dithering came up before (when the world and we were younger) the idea was that a leap second would rather amount to the omission of one of the normal monthly dithering steps.

So be it indeed, however note an alternative strategy (proposed in precambrian times):
The current standard provides a lot of leeway in implementing UTC. That leeway could be used to address our varied concerns in diverse ways.
If politics is to triumph over process, even better is a political solution that requires no international agreement at all. For instance, we have the "Draft Alternate Proposal" from the final slide of the Torino Colloquium: "Evolve from the current UTC Standard by transition to Temps International (TI) [...] TI should be a continuous atomic time scale, without Leap Seconds, that is synchronized with UTC at the time of transition." (http://www.inrim.it/luc/cesio/itu/closure.pdf)
"Universal Time" *means* "mean solar time". It is natural to call something that is in no way mean solar time something other than universal time.
