Are we going to have a 'scripts' repository (see bug 64871
<https://bugzilla.wikimedia.org/show_bug.cgi?id=64871>), really?
Pros:
* the size of the package would decrease dramatically (more than half
of the overall), becoming a cleaner environment for experienced
users who only run their own scripts;
* we could move most scripts to subdirectories without running into
maintainability issues.
Cons:
* Gerrit patches that change both scripts and core files would have to
be split in two;
* less experienced users (who often use the bundled scripts) would
have to fetch dependencies.
