It covers a general DAG and is somewhat easier to use in terms of UX than the parentmap, but can provide the same functionality with a multi-step rebase.
  
  Yeah, something like `--preserve-parent XXX` where XXX is a set a revs to "preserve". When rebasing a revision, if it has parents in XXX we keep them (and rebase the other). if no parent are in XXX, we don't care.
