During normal operation, GnuPG is intended to read the user's secret
keyring and open and use network connections. In some cases, GPG is
intended to do both in the same execution (e.g. decrypting a
public-key-encrypted message, then verifying a signature containing a
keyserver URL).

The consequences of GPG being compromised are so severe that I don't
see a benefit in trying to protect the surrounding system from a
compromised GPG process.
