For non trivial or chore updates a second pair of eyes is always a good idea. But it’s not possible to scale out “everybody reads everything” to a large N. The problem is that nobody could keep up with that ad the reader when there are some huge number of things to read. That’s why we delegate, create docs, and have overview sessions.
