DNAMEs do not redirect their own name, so neither a DNAME at the zone
apex (which is legal) nor one in the parent would have the effect of
a "CNAME at the apex".

A *CNAME* in the parent would, but only as long as you didn't mind
losing all the rest of the zone.

This is, of course, the usual solution.
