In context my statement was:

"By comparison, a leap second is introduced by a central authority and is ignored by microwave ovens and set-top boxes and in general most clocks worldwide. Even if one-a-day is introduced this would be the case."

I was discussing one-a-day leap-seconds, that is, when the length-of-day becomes 86401 SI-seconds.

By comparison, leap-hour-proxies like rubber timezones would originate from no central authority and could be ignored by no stake-holders for any purposes.

This is also a rhetorical discussion. The problems resulting from embargoing leap seconds would start immediately. Astronomers are just the canaries in the coal mine.
