From what I've experienced using the arquillian-jacoco 1.0.0.Alpha5 release I would say it would be way to early to call for a 1.0.0.Final release. Seems like there is some issues still to be resolved before going final along with proper documentation. But it would be nice however if the 0.6.2 support could be released in a new Alpha version.
Working on pushing out Alpha6 now. It will include the 0.6.3 support.
