It's a matter of preference: the majority of Ant's
developers aren't keen on having the functionality.
Further, while the syntax ${${foo}.bar} seems
straightforward, it is arguably ambiguous. You can
choose to believe that this is a nested property
expression, but some might disagree and see things
differently. In any event, Ant's property handling
API has been redesigned to accommodate this, and it is
available in the experimental props antlib, which
rather than being considered a hack, is a way to
support this use case at the user's discretion without
forcing it on all Ant users.
