The notion of "task" has been deprecated for a long time because
the word is used for different things. The new word is "packagegroup"
which describes the usage of "task-*" in a more obvious way. Dora
and master builds can fully use packagegroup-* for everything and
for edison we would need to spend some time to add a provides for
packagegroup-* to the task- group. I don't intend to work on the
edison part right now.
