Not for Ant's core, but as a separate Ant library.  This will allow the
tasks to be updated on a more frequent basis and they may take advantage
if commons-compress releases will be more frequent than Ant releases
(which is likely if only because of Ant's slow cycle).

And then there is this strong reluctance (which I share) of Ant
developers to introduce any external dependencies for core tasks.

That's what the comment in the code say as well, it just doesn't look
that way 8-)

same here

That's what I assume as well, I'm just hoping that anybody else would
know for sure before I "fix" it.
