Well, I am maintaining lots of Zero builds, and at least x86_64 Zero works. This should cover the 
majority of potential problems with Zero on other arches too. The rest of the problems, if any, 
would likely come from massive rebuilds of Java packages using the Zero VM in the system JDK, which 
would be hard to easily test.

Adrian, tell us if you can/want to do that :) But I think it would be fine as it is.
