package changes and comps

Hi Not sure whether fedmsg or something else can handle this but throwing it out there if anyone is interested. I just split up a package which is listed in comps.xml and it would have been quite easy to miss adding the sub package (deja-dup-nautilus in this case) and new users wouldn't get the nautilus extension. IIRC this happened with file-roller earlier. Would it be feasible to check when spec file changes intro a new sub package, verify that the package is listed in comps and send a note to the package maintainer reminding them about potential changes they might need to make in comps? Also when someone is introducing a new package, a similar note would be useful Rahul
