Indeed, I can’t remember a single time where I’ve needed that, let alone actually realized the restriction existed.  But now that you mention it, I do remember discussions in favor of the more restricted syntax when the feature was originally being debated.  I don’t remember the reasons though - it well could have been an abundance of caution over how far to take the new syntax (and understanding of course that it’s easier to relax than restrict).
