Further on in the email chain, it looks like there is momentum for hard forking under another project named 'SpotBugs' [1, 2]. I hope to see the project live on as it has been useful. Other tools like Google's Error Prone and IntelliJ's inspection toolset are awesome, and FindBugs is complimentary to them.
