would -C have created it if it didn't exist?
if C means change to a dir first, I would read that as implying that the dir 
exists to cd into.
otherwise it's a convenience for this:
cd srcdir ; tar cf - . |( [ -d destdir ] || mkdir -p destdir ;cd destdir ; 
tar xpf - )
which I'd agree is no longer a slight convenience

In any event, we now know the feature was there, merely not demonstrated.
