Fair enough, Aryeh. I was arguing for using lang, which which the standards
require, not for hreflang, which they do not (although I don't see any reason
not to use HTML markup such as hreflang to tag known page elements, when each
page already has about 30 kB of non-content markup, scripts, and style sheets).

I don't accept that there's a useful concept of regular browser. People using
screen readers use them to operate (“regular”) desktop browsers. Is the Google
search indexer a regular browser, or is Google Language Tools? Or Mobile Safari
on an iphone used by a blind person? What about the screenscrapers used by the
countless sites that syndicate wikimedia sites?

Right.

We're not experts, and we don't have a detailed comprehensive survey of
accessibility software and hardware capabilities, nor are we ever likely to.
The best we can do is follow accepted, unchallenged standards. If you do have
information that disputes them, I would be interested. But grumbling about them
is unhelpful.
