Should vert.x add support for stm(software transaction memory) 

    I dare think that vert.x should add support for stm(software transaction memory) for while developing we could not ignore the configuration for database transaction currently most of us make choice to integration with spring framework(for it provide the transaction feature) but it also has us to include many third party framework jar to support 
it(or integrated with jboss transcation) and most also have us to make vert.x under the embedded mod for developing.
    As akka itself provides support for stm, so why not vert.x adds support for it(or provide the third party solution for it in the manual)
