I see your point, Francisco, but the difference is this: we have a
single server which is considered canonical; you and I have *copies* of
the repo, and we can do as we like to our local version. Others have no
knowledge of the state of our repo.  When that single point of failure,
the savannah server, goes offline, so does our definitive version of
lilypond.  The trust comes from access to a single physical version of
the source.

In a truly distributed, not just widely copied, VCS, the trust is based,
for example, on credentials: only certain people can make changes, using
some irrefutable signature. The changes are propagated in a torrent, so
the repository exists in its canonical form on many machines, any one of
which can be unavailable without compromising the whole.
