    Description

      In SERVER-39567 we changed min()/max() to require a hint(), but kay.kim discovered that this is not enforced when IDHACK is used.

      I don't think there's an incorrect results bug here (similar to the linked ticket) but this is undesirable.

      Repro:

      db.c.find({_id: 5}).max({_id: 1}).explain()
