Question: how are the versions of the packages added to the variable? is there a nice automatic solution or has it to be done by hand before of the deployment?

[utnapischtim]

my two cents: a group name would be nice. we have "Site Management", "User Management" but the package -> version has no group name. maybe something like "Dev Management" and the sub name "Package versions" to make it open for other possible use cases.
