Is there a link to the new proposed policy.. I think I saw it posted but can't

... perhaps on debian systems. It does make it easy to deploy java
applications especially if you want to be as 100% java as possible.
I don't think we will get past this issue though. The WAR approach does allow
one VM to load code from multiple places due to the classloader approach.
If we want to push this 100% we will have to use a more modern classloader (IMO
the standard classloader suck).

Not necessarilly. In the above scenario they are needed.

There are advantages. Again nothing is black and white. :)
