Exactly right :) Your RPM doesn’t need to worry about it (in fact, can’t - there’s no way at package build time to determine what XDG will resolve to at runtime), and following the directory rules means the system can show per-app disk usage, allow users to clear the cache directory (even while the app is still installed, that’s why it’s called “cache” - no data in cache should be something that can’t be deleted between invocations without losing user data), allow users to reset the app configuration (again, while the app is still installed - resetting the configuration without affecting the user data; that’s why you should only put configuration settings in the config dir, and put user data into the data dir) can have per-app backup and restore and can clear app data on app uninstall, have per-TOH “profiles" for certain apps (example: TODO list with work TOH shows different contents than TODO list with party TOH), etc… And as Ove pointed out, this is not done yet, but will be done at some point in the future (having apps put their data into the right subfolder [named like the app name] of XDG basedir is a prerequisite for that) - in any case, something that app developers shouldn’t need to worry about implementing themselves, just follow the XDG basedir spec with the addition of using the app name as subdirectory (as described in the Harbour FAQ) and expect that the system will handle clearing and backing up of cache, config and data (eventually).
