As far as I know, that patch + design has been abandoned.
There was a discussion about adding it without fundamentally changing the
DAGImpl (and task recovery etc).
The VertexManager already allows you to have a vertex without a task in it,
without giving up on being a participant in the data movement events.
However, there are no immediate takers for the new approach (which is additive,
so needs no significant refactoring changes) and this feature did not have
anyone waiting for it.
Cheers,
