Regarding the proposed USPS changes, they are for labeling ORM-D materials. By 2015, that category will be eliminated by the Department of Transportation, so materials that currently use the ORM-D label will have to be marked with the familiar "sideways square" with the appropriate boxes filled in.
By the way, there's no mystery about what changes are pending to the Post Office's Mailing Standards Department. Like all federal agencies, the proposals have to be published in the Federal Register and an appropriate comment period must be open. You can see what's been published in the Federal Register here:
