I wasn't referring to any particular language feature. I was saying  
that we should be informed and even be swayed by how markup gets used  
in practice even if you consider the usage "poor". It would be  
foolish to ignore actual usage.

There's a big difference in installing curb-cuts as part of the  
routine paving work and chiseling them in afterwards. Installing them  
as part of the routine is relative cheap while chiseling them in  
afterwards is relatively expensive.

If we apply the curb-cut analogy to HTML, the conclusion I draw is  
that we should move to markup with built-in accessibility roles as  
part of the routine authoring process instead of advocating after-the- 
fact chiseling with role=''. That is, we should push <progress>  
instead of a bunch of divs and spans with role='wairole:progressbar'.

I'm not making market *share* arguments. I'm arguing that we should  
be informed and potentially swayed by how markup features are used in  
practice. That is, how they are doing in the "market". Pretending  
that the design accessibility features cannot fail when exposed to  
the people out there (i.e. the market) makes no sense.
