Comment (by swissspidy):

 > Of course we could also count the items in the array and use isset() if
 it is just 1. But the approach of providing a string brings a similar
 performance improvement and is a more intuitive API.

 I'd suggest doing both, so that plugins and themes doing that will
 automatically benefit from such an enhancement too without having to do
 any code changes.
