Agree we should deprecate this. Could you rebase it? |

Oops, missing CHANGELOG/release notes entry. Could you add it? |

Reliant on rails#15747 but pulled to a separate PR to reduce noise. `has_many :through` associations have the undocumented behavior of automatically detecting counter caches. However, the way in which it does so is inconsistent with counter caches everywhere else, and doesn't actually work consistently. As with normal `has_many` associations, the user should specify the counter cache on the `belongs_to`, if they'd like it updated.
