The algorithm has been used in production in other codepaths like
patch-ids and replace-object, so correctness-wise it should be fine
to turn it on.  I think nobody has bothered to benchmark with and
without the environment to see if it is really worth the complexity.

It may be a good idea to try doing so, now you have noticed it ;-).
