It doesn't allow that at present.

I think the array literal parser would reject this on the grounds that
the brace structure doesn't match the dimension specifiers. You could
modify that check to respect zero length in dimensions other than the
innermost one, but it's hard to say whether it would be worth the
effort.
It might be instructive to hear from somebody who does (or intends to)
use multidim arrays for some practical purpose, but I don't even know
whether such a person exists within earshot of this list.
Cheers,
