Description: 

The hook classes, introduced in Convert hooks to class hooks, have been marked internal.
Hooks implemented by modules are not public API. Hook classes are therefore not supposed to be extended by contributed projects, which is also not necessary.

In the 4.0.x branch, hook classes will be marked final.

Impacts: 
Module developers
Site templates, recipes and distribution developers
