Ubuntu SC use a similar system. It uses a database to store the
informations (I think it's xapian which is used), and it's rebuild
automatically when a file is changes in /usr/share/app-install/desktop.
It's probably a better approach, but you should test the final behavior
(like the time to start, to rebuild the database ...).

Another solution is to use a cache of the /usr/share/app-install/desktop
content. Like the database usage, it's something you have to test to see
the result.
