Comment (by flixos90):

 Just left a review on the PR. It looks good so far in terms of caching
 logic, but we'll need to also take care of invalidation. This is not
 something where we should only rely on expiration of the transient, as
 that would still mean we'd sometimes serve stale values for something that
 is user-editable.
