Comment (by spacedmonkey):

 The previous approach depended on the object cache backend automatically
 evicting stale keys, which is not always enabled by default (e.g. in Redis
 or Valkey). Even when eviction occurred, it still led to a large number of
 cache keys being generated. The new approach avoids this issue by reusing
 keys instead.
