 Two recent instances where a hook that is triggered in multiple places in
 core has ended up having differing parameters:

 * #38057
 * #38314

 It would be ideal to have unit test coverage which scans core's PHP files
 for all instances of `do_action` and `apply_filters`, filters hooks that
 occur multiple times, and then verifies that every instance of the hook
 accepts the same number of parameters.
