I have no opinion about the package name, but I think the most
important question is the name of the command used to invoke it. We
should make that name as natural and easy to remember as we can.
Included is the latest version including
(unless (fboundp 'irc) (defalias 'irc 'rcirc))
To minimize confusion, I think it makes sense to keep the original
package name.
