It is impractical to install all of the available tools that diffoscope
supports, as it supports an absurd number of file formats and thus uses
a very large number of tools.

You can call "diffoscope --list-missing" to give suggestions about
packages you might want to add, and as you've observed, diffoscope
suggests what to install to get better support for the files it is
currently testing.
