ant-contrib contains programming concepts that are at
odds with Ant's fundamental design. e.g. 1 <if> vs.
<target depends if/unless>. e.g. 2 <for/foreach> vs.
Java-implemented tasks using <fileset> or other types.
<var> specifically exists to defeat Ant's concept of
property immutability. For the most part one can get
by without ant-contrib, but in a realistic world,
sometimes it's just easiest to use it. Some of the
other ant-contrib tasks just might be considered too
specialized for Ant core. Ant's own distribution
contains many things it shouldn't as it is; future
versions will be looking to streamline by moving many
of what are optional tasks today to antlibs that can
be used optionally.

I guess that was kind of my point wrt ant-contrib
being as commonly used as it is. You never know what
other project will be relying on it; one might
therefore consider it to be a "standard extension," as
it were.

Ant's SVN HEAD contains a <classloader> task that can
do some of these things. I'm not sure who uses it; I
don't. It's been in HEAD and marked as experimental
for some years now; it may well ship with 1.7 . I'll
see what info I can dig up on this task.

You could, by forking Ant. Ant doesn't provide <ant
fork="true">, however. One would have to configure
the <java> task. The problem has been that nobody
sees fit to keep track of the various cmdline options
to forking Ant in code. This might actually make a
decent antlib, however, as keeping such code in one
isolated place would be easier. I'll have to keep
this in mind...
