Comment:

 Recap of discussion in this ticket and elsewhere:

 Advantages of introducing this filter:

  * The `$template` array can be used in a client-side templating app.
  * The `$template` array can be used in a debugging plugin.
  * Allows language-specific versions of template files in multilingual
 plugins.
  * Allows control over cascading and priority of template files.

 Potential disadvantages of introducing this filter:

  * Allows abuse of control over the priority of template files.
  * Alows template files to be removed, thus removing consistency.

 Bear in mind that the `template_include` and `{type}_template` filters
 negate any arguments against such a filter allowing the template hierarchy
 to be abused. It already can be.

 I'm strongly in favour of adding this filter into 4.4.
 [attachment:template_hierarchy.6.diff] refreshes the patch.

 Related tickets which I've been considering holistically along with this:

  * #12877
  * #13239
  * #22355

 Going to give this a final discussion in the dev chat this evening.
