An early post from Hironori Bono:

Ian showing interest, but also defensiveness:

The chilling effect:

This chilling effect is not based on actual costs to browser vendors.

Very simple fixes to the existing spec are neglected:

Neglected is not the right word: they are discouraged.


WCAG requires that content be labeled so as to be "Programmatically 
Determined". Serialization is a valid use case.

So is making canvas based UI accessible:
"Guideline 8. Ensure direct accessibility of embedded user interfaces."

Vendors should be promoting APIs to share information about the GUI, as 
stated in WAI-USERAGENT:
Guideline 6. Implement interoperable application programming interfaces
"Programmatic access" is very much encouraged.

Currently, programmatic access to input devices, and to form elements,
specifically <input type="text"> <textarea> and <div contentEditable> is 
severely restricted.

That's something that additional work in the IME realm can provide.

I can not, at current, scroll the text inside of <input type="text">, 
accurately measure
the width of that text, nor determine where the cursor is in that text 


I've worked very hard on whatwg and w3c lists to address real, 
identifiable usability to concerns,
and encountered incredible push-back under the guise of questioning "Use 
Case" validity.

As I've stated, many times, I no longer put forward Canvas as a use 
case, in my proposals.

Fortunately, I don't need to: The API deficiencies we're exploring are 
deficiencies in other web technologies.

The current debate is as to whether web programmers may develop their 
own IME, and whether
it's a valid use of the scripting environment. I feel that it's valid, 
some browser vendors do not.
