Just to be clear, I would not want the browser to refuse to render the
page even if a critical alt is missing. That would be a situation where
the cure is worse than the disease.

I want the @alt to be mandatory for critical content for conformance for
WCAG 1.0 and also [insert new attribute here] for WCAG 2.0.

That puts accessibility into the right domain. Should the browser still
continue to render pages that don't conform, yes. Should authors right
better code and mark-up content in a proper way, yes. Should the browser
not render a page that is not proper or does not conform? No.
