No, there are no plans to continue work on this project. However some of the concepts are potentially going to be added to other projects, although not in the short term.
Which parts of the functionality are you interested in?
the scenario design, model design and simulation of the scenarios is very interesting.
BPEL is a little bit outdated.
Do you have an idea, why it hasnot been widely used? From my perspective it is very helpful, to define and control changes to ones SOA landscape. I haven't found a tool like JBoss Savara, which helps during the definition of a holistic architecture.
It could also be helpful in designing and verifying a micro service architecture, before you start implementing it.
We always felt the approach had potential, but no idea why it didn't get any adoption.
Will keep you updated if similar capabilities become available in other projects.
