Agree with Mike.  Let's be careful here.  A lot of sites use both TH and
H tags to assist AT navigation...

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.
