[tor-relays] Why do 40% of Tor exits uses 8.8.8.8 for DNS resolving ?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Reading [1] I do wonder about that. Why do Tor exit relay operators avoid installing a local resolver - or at least simple a cache as shown in [2] ? Adding different nameserver= lines to /etc/resolv.conf than 8.8.8.8 shouldn't be a big thing, or ?
