True.

I never assumed that 8-)

You can't replace all of the current createXYZ methods as some of them
would return things that Ant's core wasn't able to create at all
(inner classes for example) - or do special things like the Path
creating methods that join all subelements.

I'd prefer to document the limitation and probably live with
explicitly noting that ant-type won't work for the nested elements
that are affected.

We'll also have to explain why

<copy>
  <fileset ant-type="zipfileset" src="foo.zip" prefix="bar"/>
</copy>

won't work as expected (because <copy> unlike <zip> doesn't know
anything about ZipFileSet and ZipFileSet is no drop-in replacement for
FileSet).
