Perhaps not in the field of people who write their own websites by hand,  
but I think in the general case they will clearly differ.

Which reinforces the argument. While I write my own CSS for content I  
produce for my own use, most of the content published by Opera is done  
with a stylesheet produced by one of a very few people. This is even more  
the case for large organisations, social networking and news sites,  
Wikipedia and educational material and so on.

In most corporate environments, it doesn't work like that. In many  
organisations that have some commitment to accessibility (even the ones  
who don't get i) there is a clear policy of having a few "experts"  
(increasingly they actually are) create a set of widgets - analagous to  
the jquery experience Tab mentioned.

Sure. But vast swathes of HTML are not written by people from scratch, but  
relying on scripts, style snippets or style sheets, and templates which  
someone wrote for them - both to make life easier and as part of  
quality-controlled workflows.

There will certainly be people who don't care about accessibility and  
don't do anything at all (just as there are for simple things like alt  
attributes), and others who care but get it wrong, but aligning with the  
common model for those who care and are trying to get it right strikes me  
as a big benefit.
