Comment (by r-a-y):

 I'm concerned about the cache purging strategy when we use
 `bp_core_get_incremented_cache()` to fetch the group cache, especially
 when working with the edit group slug ticket (#6014).

 If group A changes their slug from `old-slug` to `new-slug` and Group B is
 created with the slug `old-slug`.  Wouldn't using
 `BP_Groups_Group::group_exists( 'old-slug' )` return Group A due to how
 the cache reference due to how the cache key in
 `bp_core_get_incremented_cache()` works?

 How does cache invalidation work here?
