It's quite concerning that ailin-nemui, who made the prior commit migrating to Libera currently isn't listed as part of the irssi organization[1]. According to GitHub stats, this is the person behind most of the code in irssi[2].

My bad, I didn't know that was a thing.
In all likelihood, they probably just had their commit access revoked, or are just hiding their membership as part of the organization.
