The pages for pseudo-packages do not display the official descriptions
and maintainers for them, for example:

https://tracker.debian.org/pkg/tracker.debian.org

There are plain text files with maintainers and descriptions here:

https://bugs.debian.org/pseudopackages/pseudo-packages.description
https://bugs.debian.org/pseudopackages/pseudo-packages.maintainers

I don't know if distro-tracker supports translations but if so, the
official translations of the pseudo-package descriptions are here:
