While there's no *need* for a $server.port or .group or .desc because they either don't apply or we have $port, there is a *need* for us to get the server password, the login method, and the login password, since we can use /server -l without the server list.
That being said I never saw anyone requesting to be able to get the server password with $serverpass but it could definitely be a thing, same for $servermethod and $servermethodpass although these last two names, while consistent, are a bit ugly. I was thinking maybe $server.pass .method and .methodpass could be a thing, $mouse has properties like that without taking a parameter.
