Very well, then: why should specific, large scale changes be discussed?
I'm intentionally ignoring the implication that this specific change was a "large scale" one.
Because a community is made up of its users, and if people find the changes negative enough, they will stop using the site.
Has anyone yet mentioned or reported that for the last couple days, the "karma for last 30 days" is showing zero for everyone? And that we no longer can see the top contributors for the last 30 days either?
Do we have an explanation or estimation for a bugfix on this?
