It is also used by LibreOffice (or under-maintained OpenOffice).

There can be benefits of container compressors like zip and 7z:

Tar comes from Tape Archiver. It works sequential. So to dig out just 
one file it has to read over all the archive until that file comes.

Zip instead has the contents directory at a central place, as far as I 
vaguely remember at the end of the file. That is one of the reasons 
OpenOffice developers back then chose it.

Well of course there are other containers as well like dar for disk 
archiver.

There is a crazy amount of tools in that area. I benchmarked some of 
them quite some time ago¹.

[1] outdated, I wrote a Linux User article about those quite some time 
ago, the packbench program may still work tough and could be enhanced, 
adapted to support newer stuff:

And yeah, I know Gitorius is gone and I intend to upload everything to 
Gitlab at some time.
