I often leave comments similar to this to inform close voters that I'm working on a solution for instance. Since we are a community and are trying to work together for the common good, this makes perfect sense to me. It's not an attempt to mislead or impose an opinion.
It's simply a way to communicate with the community. I personally would hesitate to edit a post that wasn't a CW in this fashion, however I understand the motivation to attempt to offset the tendency of many to robot review without reading the comments. One of the reasons I push to have users edit information into there posts is that comments aren't always read (the other being comment deletion of course)
