Some people are saying that they want to keep the mailing list because the IRC network might be malfunctioning at some given time.
To this, I want to say that you don't need a mailing list to report problems with the IRC. The mailing list is to talk to everyone (that is subscribed). If you want to report a problem with the IRC, you send a mail to root@tilde.club .
So, this argument, to support of the mailing list, is false.
