The patch needs to update DateRangePlainFormatter.php too as said in #6. However, the DateRangeDefaultFormatter.php no longer needs to be updated.
I agree with #4 that the actual frontend behavior is fine. However, I think the main problem we are facing here is that when one needs to customize the output of range date fields on Twig templates, it's not usable to have to check out whether the start_date and the end_date are set or not. This forces you to write complex Twig code that one wouldn't want to write.
