- For consistency, functions should always return null on non-existing data. - WordPressPluginUpdateBridge appears to have used its own cache instance in the past. Obviously not used anymore. - Since $key can be anything, the cache implementation must ensure to assign the related data reliably; most commonly by serializing and hashing the key in an appropriate way. - Even though the default path for storage is perfectly fine, some people may want to use a different location. This is an example how a cache implementation is responsible for its requirements.
