As far as I can tell, lzip is only used on Linux. There are no tools that ship with macOS or Windows (out of the box) that can decode it.

Adopting lzip as the primary format at this point seems like a statement that only Linux matters.

Neither of those systems come with a compiler out of the box either.  On
MacOS, it takes less than 1.5 seconds to install lzip:

$ time brew install lzip

If you have trouble unpacking .tar.lz files - just point your browser to

https://github.com/eggert/tz/tree/2016g

and get whatever individual files you need.

BTW,

$ wget https://github.com/eggert/tz/archive/2016g.zip

will download all files in a .zip archive.

Sorry, my timing was off because I already had the source cached.   With
downloading, it takes about 1.8s:

$ time brew install lzip

Doesn't ship with "Linux" out of the box, either. At least, on my
machine it's not present and I've done nothing special to exclude it...
Ubuntu has a half dozen packages for different versions of it (most of
which seem to be in "universe" rather than the main distribution), with
no clear guidance on which one I should want to install. [It's clear
enough, to be fair, what the actual differences between them *are*, but
it's not clear if these differences have any impact on performance or
not, and overall I'm completely mystified at the decision to *package*
them.]

While it seems to be a bit bleeding-edge, I don't see how it's less so
for Linux than for other operating systems. Also I don't see why a
"primary" format means that only platforms supporting that format, 'out
of the box' or otherwise, matter, while other distribution formats are
still fully supported. Seems like it creates a bit of a chicken-and-egg
dilemma towards ever migrating anyone to new formats.
