The desktop file method was chosen because it was said that they avoid duplicate translation work. See last point of the Introduction https://api.kde.org/frameworks/knewstuff/html/classKMoreTools.html ("Reduce translation effort by re-using .desktop files of the services added to the menu."). Since the goal of KMoreTools is to present applications that are not installed, I currently see no other way to ship all the desktop files.

To be of use in KMoreTools there should be an offline database with all needed applications and descriptions. How will this database be filled with new applications? Maybe you can point me to some suitable documentation?
  
  
  The idea is that you don't care about the database. The appstream database is downloaded/updated like the list of the packages provided by the package manager. You just query the database; check what plasma-discover does, for example. @mak , who maintain many stuff related with the appstream technology, may help as well.
