Not in general. It will help only in the case where there are only one
level of hostnames below the top level domain. It won't help in
the cases where that's deeper.
  

It still helps, it just doesn't make it possible to cover the entire 
multilevel domain with a single ADSP record; you need to have a record 
for each subdomain (one level up from the leaf nodes in the tree).  But 
are still substantially fewer records that need to be published in this 
case.

People whose work environments consist solely of three level
hostnames see it as a magic bullet. Those who don't, see it as
a hack that adds complexity for recipients without buying the
senders any functionality they didn't already have via less
intrusive methods.
  

Intrusive?  How does this intrude?
