These things cost effectively nothing in terms of heap or during handling but their handling actually does free memory. They should never be rejected. Otherwise a storm of 429s might lead to some sticky memory consumption until the contexts time out.
We wouldn't see this currently as we don't log any warnings (just debug+trace level messages here) if freeing a context fails.
