As far as an end-user, probably no impact at all.

Well, until at least 1.7 is stabilized, I don't see build.xml rewriting 
going away entirely.

One possibility I see, is in our java-ant-2.eclass, we could check for 
the version of ant we're using. If we're using < 1.7, do the traditional 
rewriting.  Otherwise, we use the new ant.build.javac stuff.
