Comment (by thomaswm):

 The internals of `domain_exists()` have been rewritten in [37620]. Instead
 of hard-coded DB queries, it now uses `get_sites()`. That should make it
 pretty easy to implement this:

 > Allow the current $site_id argument to be null (for all), or an array
 (for many), in addition to the current int expectation.
