Scratch that. It would be better for merge strategy just to check for
defined set of "links" and "notes", e.g. "prior" (pu-prior) and
"original" (cherrypick).

But there would be problem with connectivity provided by "link" relations,
namely info/grafts file, which deal only with parents. For example when we
cauterize history using grafts (e.g. for shallow clone) the "link" like
"prior" reaching to the cut-off part of the history might make your day ;-)

Well, we could always drop all the connectivity, and make
  link sha1 description...
shortcut for
  note link sha1 description...
