Are we only talking about table headers? If so, I would be concerned that 
deprecating headers could cause problems with older screen readers that 
don't recognize the scope attribute. It would be worthwhile to check with 
Freedom Scientific and GW Micro to see how far back scope is recognized. 

If we are also talking about content headers, then this would have a 
significantly negative impact on screen reader users. Not everyone knows 
about using headers for navigation and scanning, but those who do find them 
useful. Headers also seem to be the one dependable way to navigate across 
<shudder> frames, which are still used in some applications.
