Comment (by johnbillion):

 One concern I have is that with this change in place,
 `wp_generate_uuid4()` now relies on a pluggable function. This means it
 would break any code that calls `wp_generate_uuid4()` before the
 `plugins_loaded` hook. What's the likelihood of this? Low, but perhaps a
 plugin somewhere is generating a UUID for each request for logging
 purposes.
