The (full and ordered) history may be hard to find without any
Message-ID in commit messages. The Lore links keep that information (in
the commit message) and redirect to the related archived email thread,
which is very handy. For instance, Linus can rely on those links to
judge the quality of a patch:

I don't know, but it doesn't hurt. This way, if you're using git am
without b4 am -l (or forgot to add links manually), the history is still
pointed out by these self-reference links. I find it convenient and it
is a safeguard to not forget them, no matter who takes the patches.
