Comment:
Testing `18536.5.diff`, it breaks in the situation that a plugin has
filtered `'posts_request'` and changed the selected fields.
It would be difficult to check for fields after this filter.. should we
expect a filter on `'posts_request'` to know the pitfalls and modify the
query accordingly so it can still be optimized?
It looks like filtering `'post_fields'` or `'posts_fields_request'` in
addition to `'posts_request'` could shortcut the `$expand_ids`
functionality..
