@muvlon @jwildeboer As stated earlier. Message history is not a required feature. You simply never go into a social event and ask people for their discussion history for the evening.
I don't know why people using irc think this should be the norm. If you want message history, there are frequently logs for heavily used channels.
Let me ask this question, do you read _every_ line of text that was written while you were absent? And then I'd ask "Do you _need_ to read every line?"
@miah @jwildeboer No, I don't read every line, but I read a lot of scrollback. And I did run my own bouncer for almost the entire time I was using IRC. And when I didn't, it felt like a decidedly "second class" experience.
