I have moved the code and tests over.

I think it's fine to break things into separately versioned external components when we have reuse (or great potential of reuse). The ejb3 timer implementation though is unlikely to be useful to anyone other than our impl. So using package separation for that case seems more than adequate (at least now)

Ideally we start with an agreed upon requirements doc, then a set of docs detailing the abstract design. Then when code is created we try to reflect the doc information in comments and javadoc.  Any significant refactor then can be reviewed against that information.

The burden is ultimately on the person sending in the pull request / patch to break up changes in such a way that they are applied in reasonable time frames. For example simple bug fixes require much less review than a complete re-architecture of EE proxies.
