Most applications clog up the cache space on your device’s memory. You have to delete the cache manually which is not convenient. Fedilab is one of the few applications that has a self-cleaning cache function when exiting the application. Why don’t many other apps have a feature to disable caching or self-clear the cache?
From the QA perspective, I think most developers assume the cache mechanism will keep working the way it does on their device in their short development cycle, and don’t really consider whether it will eventually break, when applied to millions of different configurations for an extended time, with differing usage behaviors
