Correct me if I'm wrong, but as I understand it the tzfile in the
tzone package is not used to update the system time - that relies on
NTP or similar. Rather, the leap second info in the tzone files is
made available for applications to use, primarily for calculating time
differences in the past.

> "Linux systems now know about the leap second" -- this is a very dangerous assumption. And one reason why leap seconds have gotten out of hand the past decade.

There must be millions (billions?) of embedded or isolated systems -- from web servers to desktops to military systems to gadgets to Raspberry Pi's to mobile phones, that have not, and will not ever receive this update.
