That's what the ircv3 guys did. I think it's a cancerous attitude: you get your protocol implemented regardless of whether it's good or not, since most managers of open source software can't say no to free code
I don’t think anyone in the IRCv3 team has provided free code to any other project just for implementing IRCv3 functionality. In fact, the opposite is true, most projects have to spend significant effort to support it — but believe that it is worth it.
