This is one of those instances of pure non-sense that I hope will drive rich discussion.
The whole notion of forcing users to change their behavior by placing obstacles in their way is futile in my experience. It's a grave misunderstanding of who users are and how to design for them.
Forcing users to do what you want them to is how you get desire paths [1]
I worked at a company that tried something similar.
The result was that individual teams set up their own off-the-record private Slack workspaces or Discords so they could regain some control over their conversation history. Obviously not great from a company information security perspective, but many managers looked the other way because they just wanted to get their work done without worrying about conversation history arbitrarily disappearing.
The idea that you can force people to produce better documentation by making their lives more difficult never really works out.
Also as the sibling comment is saying, you won't change the culture of an organization only by an UX change or a software change, that can help, but that won't be enough
