The commit message serves as an historical record of why a change was
made; depending on an external service to provide this information when
it can quite easily be included in the commit itself lessens the value
of the commit message.

If you look at other commits in git.git you will see that there is a
strong preference for summarising the discussion and rationale for a
commit in its message.
