Suggestion

All the application data currently persists when uninstalling unless --delete-data is used. Uninstall should by default remove the app cache directory.

The element matrix client recently became unusable due to some shader cache issue and removing the cache made the application usable again. Unfortunately in this case the cache wasn't in the standard directory but it shows that caches can be the source of bugs, or removing caches can sometimes work around issues.

Users should not be aware of concepts like caches and their usual process of fixing things is removing and installing something again. If that process would wipe the cache, the chances of a user ending up with a working app again is higher.

Seems reasonable.

Note that in GNOME we have the "Clear Cache" option (Settings > Apps > AnApp > Storage). However, it might be interesting if you open an issue in GNOME about this because, in my opinion, reinstalling an app is not better if the cause is only the cache (that means redownloading the app).
