Using special references in the free-form area of a commit is akin to
using X-... headerfields in E-mail with all the assorted mess:
- No strict definition of what it means.
- Diverging porcelain implementations making use of the field in ever so
  slightly changing ways over the years.
- You cannot rely on the field being always available.
- Automated "renumbering" becomes difficult at best.

What we want are concise and unambiguous definitions which allow us to
build tools that operate predictably on them now, and will operate
predictably on them in the future.

Things like rebase/filter-branch/stgit mess that up because they don't
know if the hash in the free-form should be altered.
Also, there is no automated way to actually fetch missing branches we
cherry-picked from this way.
