I don't disagree.

The JAR built by this approach is here:
https://search.maven.org/artifact/org.python/jython-slim/2.7.2b2/jar

I have successfully cited it as a dependency in (very simple) Maven and Gradle projects. It be interested in knowing whether this hits the spot for more complex uses.

I do not think the original question "why so many", in the other JARs, has been answered. I'd like to reduce this to the absolute minimum in work after 2.7.2. There is perhaps not an absolutely correct way to identify that minimum.
