Spring Roo + Vaadin Add-on

In this article https://vaadin.com/springroo, towards the bottom of the page it says [b]
[size=5]

[/size]Spring security is not supported in the current version.
[/b]

Does anyone who works with or for Vaadin ltd have any updates on when this will be supported. I would like to have Roo generate all the Security components and make sure they work correctly with Vaadin?
