Or, when setting up CDI, this would remove the need to ask ask which API to use (always use the Java EE BOM with JBoss AS), and as the metadata builds, remove the need to ask the version of the spec BOM to use.
Lot's of other places where this could provide better defaulting, or remove the need to ask questions.
This also seems fairly consistent with the Forge approach - good understanding of the project in question.
