> Why not use the leap second file directly from the IERS?

Depends on the use.  If the target audience is a handful of geeks there is no 
problem.

If it gets added as a cron job to a zillion systems, there is too good a 
chance that something will screwup and DoS their server.

Packaging it with the tzdata seemed like a way to avoid that problem.

If there is a need to run something like a cron job, I think each distro 
should host a copy of the file for their users.

It's possible I'm being overly paranoid.  There are already quite a few ugly 
examples on the wiki NTP abuse page.  I'd be happier if my name as part of 
this discussion didn't get added to another one.

Consider the case of a stupid bug in a widely deployed IoT device.
