I suppose that's a reflection of the state of the IRC ecosystem, which is stagnant and slowly dying. The ircv3 project, while well-intentioned, will never result in the revitalization of IRC.
I really like IRC but the ux story is pretty bad by modern standards. Users expect seamless multi device sync, for one. You can achieve a poor facsimile of this with a bnc and a shell account but it's not a great experience.
It's little wonder to me that discord and slack have eaten IRC's lunch, sadly.
