 I might be missing something, but wouldn't using these hooks to replace a
 single `copy_dir()` call, while technically possible, require recreating
 the entire core, plugin, and theme update processes? That seems like quite
 an overkill and a challenge to maintain.

 Could there be an easier, more reliable solution to replace the
 `copy_dir()` usage in this context?
