Yes it does, just not a useful one.

What do you mean by "no space"? If you take the default for SPACE on a
DASD request with a disposition of NEW, then the allocation will fail
because absolute track 0 is not available. Do you mean that the dataset
doesn't exist?

That makes no sense. If you delete and reallocate, that doesn't use any
more space than if you pass. Further, if you don't reuse it, or if there
is an intervening step that doesn't use it, then you have wasted the
expensive disk space.
