It somehow seems backward to force the real world to conform to lazy programmers, rather than the other way around.

This is largely a philosophical point of view, since the practical difference in time of not having a leap-second is so slight.

HOWEVER.....given that very few programmers actually write time routines (most grab the time from a library call), and that computer-controlled telescopes are now a high-end consumer item, it may be that more people would be inconvenienced by the lack of a leap second than would be helped.
