Keeping the latest version in the distro file causes a pull request/merge,
which like Lorenz mentioned is hookable, and it allows us to query the
version of a released package at one glance of the rosdistro file. With a
latest keyword, any tools that wanted that information would have to fetch
it from the release repository.

What I plan to add to bloom is a feature to automatically open a pull
request for you during the release process, but that will likely not land
for a few weeks.
