Why is ~/.gnupg/trustdb.gpg readable by all?

[Steven E. Harris]

The GnuPG manual mentions that the trust information is kept separate
from your public keyring, presumably to avoid spilling what you think
of others when you export your public keyring. I was surprised to
notice that the default permissions on trustdb.gpg are both group- and
world-readable. Should this file be more private? If not, what's the
motivation?
