Yes, and that's a feature, not a bug. It forces you to use chat as chat and a wiki as a wiki. You're still free to connect a logging bot.
The sibling comment talks about IRCv3 features that show a limited amount of context from immediately before you joined, which is not the same as the infinite history seen in Slack and Discord.
That's reasonable and personally I hate it when all the helpful details I need are buried in Slack history. But also it's a lot more effort. When someone has an immediate question they need help on, real time chat is an appropriate place to get help.
It takes additional effort and overhead to then go capture the pertinent details that exchange and write them in a wiki. With infinite Slack history you get a janky high noise knowledge base for "free". Huge downsides of course, but clearly it's a very popular approach.
