I apologise, I did not see that section. But if you do read the top, the RFC was last revised in 1993. That is over a decade ago. But remember, every single item in that RFC was also dreamed up by a "coding team". The RFC is no longer managed by a single entity, it is controlled by the creators of IRCds. If they did not do that, we wouldn't even be here today.

Times change, and so does the standards IRC are based on. If mIRC doesn't want to be updated every time something new and major is changed in the service it connects to then it should be made to be dynamic.

mIRC isn't the only thing that has had problems with RFCs today, people need to wake up and grasp the fact that things do change and stop hating on them (this is a general reply, not just to you). Giving more service and more choice to users is better than sticking to standards which were made in a world 10 years ago. Just think about it. If everything remained as it was 10 years ago, how different would the Internet actually be today?
