Comment (by jeremyfelt):

 Focusing on the `is_main_network()` check.

 How about this order:

 1. Introduce new constant for PRIMARY_SITE_ID that is optional via `wp-
 config.php`, `sunrise.php`, or later. Check `$current_site->id` against
 this first.
 1. Check if `1 === $current_site->id;`. If so, we can assume that site_id
 1 still exists and that it is most likely the primary network, if not the
 only network.
 1. Else, query for the smallest site_id, cache the result, and compare
 with the `$current_site->id`.
