I'm pre-1700 certified and I get it. I think it's a new thing. I didn't notice it until the last month or so at least. As far as I know, this "coordinate with a project" requirement has been around as long as I've been on here, but I think most people deal with it by ignoring it. It doesn't really make a lot of sense. There are so many projects, and so many that overlap, that at least half of profiles I've edited would theoretically "belong" to several. If I pinged all the relevant projects every time I edited one, nothing would ever get done, and indeed, people would get very irritated, I suspect. I don't know if anyone else has ever tried to do that, but most of the time when you try to do it, all you hear is crickets. The only time I've ever had a project give any input is when I tried to get a profile unprotected so I could add relationships, and, boy, suddenly I was descended upon by a whole flock of irate project people who had various sorts of input that, if I may say, did not reflect any particular knowledge of either the subject of the profile or the area they were supposed to be managing. IMO, the project system's main function in reality is to give people badges and titles, and the less interaction one has with it, the more productive one's editing is likely to be. "Coordinate" is pretty vague anyway, so I guess you can interpret it pretty freely if you want.
