Using RSS for Service Announcements

Why don't Comcast and other ISPs use locality specific RSS feeds to notify customers of upcoming schedule maintenance windows, customer service alerts, and so on? For that matter, why can't I subscribe to an RSS feed for any product I buy that alerts me to upgrades, and so on? As far as I know not even "in the RSS groove" companies do this. Create product specific RSS feeds and display them prominently in the "About" box, the product page on your Web site, and anytime the software is downloaded.
