But doesn't that go against Ant's tradition to not have auto-magic
things, but instead spell things out explicitly, usually in the build

I'd rather we extend <typedef> to accept a <fileset> of AntLib jars to
load, possibly thru META-INF/antlib.xml, than auto-magically loading
all possible antlibs visible from the classpath. At least you can see
it and start looking at the jars it loads.

How would you know looking at a build file where a task is coming from

Also, for example, I have quite a few AntLibs which are in ant/lib,
and thus on Ant's classpath, but I don't use all of them in all my
builds. They're there because it's our official supercharged
production Ant distro, but loading all of them in builds that require
none or just a few is wasteful.

I personnally want to stay in control of what gets loaded in each
build. I don't want to prevent others to do it if they fancy it, as
long as it's not forced on me. --DD
