Do you strictly need these controller hooks to distinguish updates done by the controller from other updates?

Most of the time, people are interested in e.g. any update of wiki pages or projects. Here, it is already possible to use Active Record callbacks on the models which don't require callbacks in the controller in all places that could touch these models. See https://guides.rubyonrails.org/active_record_callbacks.html for details. You could e.g. register a new hook for after_save (or after_update) or the Project model or an after_destroy hook of the Issue model.

Since these hooks are on a model level, you won't have access to the controller params though.
