I’m working on an additive trust level plugin that adds/deletes from a group depending on membership on a set of other groups (e.g., membership in `paid` and `special` also gets you into the `paid-special` group).

It’s very strange that TL promotions will trigger an `:after_save` event, but TL demotions do not trigger a `:after_destroy` event, but I’m working around that with `DiscourseEvent.on(:user_promoted)`

But that doesn’t work because the trigger gets called before the trust level is updated:
