The /map and /links commands may be blocked, but nothing ever stops anyone listing all ip's in a dns pool for irc.<ircnetwork.host>.
Meaning you would have a the ip's for their servers then can connect and in a sence get a lookup and listing of all servers, and saving the certificates for all servers.
Alternatively, there may be something you are after avaliable, or it might be updated to be better in future versions.
-edit-
Perhaps an option to accept all ip's in a given dns pool for a network that you are using to connect to the network.
