I don't think this means the end for root, which is something I think people will assume if they don't read the posts by various developers. They're expecting that this is only a minor speed bump, not a major hurdle. Given that they know about it beforehand, it shouldn't be a huge issue.
But it is nice to be informed about this so you can prepare to update your root applications and/or defer Android software updates and/or support the plucky developers who work hard to keep things going smoothly.
Of course, unless you are the owner of a Nexus device (or a recent Motorola device, or Google Play edition device), you might not be running with the latest and greatest OS version before all this becomes a non-issue.
Plus, I agree with debro regarding the state of Android and the few apps maybe not even being needed. (And I'm rocking one of the Samsung devices about which he speaks). Everything for which I needed root access in the past has become slowly integrated as a core feature, excepting for tethering which bypasses the carrier (but there have apparently been clever developments in that area since the last time I absolutely NEEDED just a brief burst of tethering).
