That is a good point. Stephen has explained his workflow, and I can see
why he wants to reference the cherry-picked commits, and how he thinks
that the referenced commits will always be available in that workflow.
And obviously in Linus's workflow such references are basically useless,
and they should just not be generated.

But what about workflows in between? When I pull from some developer who
has added a weak reference to a particular commit SHA1, but I _don't_
have that commit, my next question "OK, so what was in that commit?".
What is the mechanism by which I find out more information on that SHA1?

Using a key that is meaningful to an external database (like a bug
tracker) means that you can go to that database to look up more
information.
