That way we can make it extensible in future changes.
Now it looks like this:
<key>packages_installed</key>
<array>
<dict>
<key>pkgname</key>
<string>dash</string>
<key>short_desc</key>
<string>POSIX-compliant Unix shell ...</string>
<key>version</key>
<string>0.5.4</string>
</dict>
...
</array>
xbps list should be faster than before if a lot of packages
are installed.
