It depends who you ask, lots of people actually do not care or like threads the way they are implemented in Slack. This is basically a place where conversation just get buried.

IRC did not have threads, yet it is still there after almost 30 years.

Are we tracking the Zephyr requirements for a chat server anywhere, and assessing them against a list of candidate services?

Based on some trials at https://discord.com/channels/720317445772017664/720317445772017667/734352748396413051 I think thread support should be a requirement, and that Discord doesn't satisfy it.
