Comment (by SergeyBiryukov):

 I see two issues with [attachment:17026.diff]:
 1. It only returns 5 top pages by default, where as the current query has
 no limit.
 2. If we fix point 1, it's less scalable, since there's no way to only
 request `ID`, `post_parent`, and `post_title` fields using `get_posts()`
 without additional filtering. It'll be requesting all the fields for all
 pages.

 I guess this should wait until we allow the `fields` parameter to be an
 array, as noted in comment:1. If that isn't feasible for some reason,
 perhaps we should filter `$items` instead?
