If you set +x in modes-on-connect regular users cant get anything that can be used to cause harm to another user by /whois'ing them so to be honest i cant see what purpose you gain by disabling /whois.
set::options::dont-resolve;
If present hosts of incoming users are not resolved, can be useful if many of your users don't have a host to speed up connecting.
Note that since no resolving is done you also can't have host based allow blocks.
