Description

It seems like whenever MyConfiguration.current() is called, it gets cached indefinitely inside DEFAULT_REQUEST_CACHE. cache_timeout is ignored inside TieredCache for RequestCache. This prevents the cache from validating when used outside of the request context. Is this an expected behavior?

Research direction

Start by tracing MyConfiguration.current(), DEFAULT_REQUEST_CACHE, TieredCache, and RequestCache, focusing on behavior outside the request context. Verify whether cache_timeout is applied there and clarify the expected invalidation behavior. Done means the cache behavior matches the documented expectation and is covered by a regression test.
