Comment (by spacedmonkey):

 In [https://core.trac.wordpress.org/attachment/ticket/43941/43941.3.diff
 43941.3.diff] I have created a brand new patch after a chat IRL with
 @flixos90 and @swissspidy .

 This new patch, allows developers to register single and multiple
 defaults. For single defaults (single => true), any value that passed as
 default, is used. However, defaults (single => false) REQUIRES a numbric
 array be passed. I think that this patch is a workable solution.

 Once we are happy, I can add some unit tests.
