Isn't that kind of like saying "They're still working on HTML after 23 years"? Technically you're right, but version 1.1 of XForms was completed and published over 5 years ago.
That said, XForms is dead AFAIK, and that's not a bad thing.
Yeah, my point was more along the lines of they've been working for 10 years and gotten near zero adoption. Not saying it will fail again for sure, but if this had value, XForms would have found it. URL-encoded POST data works just fine.
