Eww is from Emacs Bzr trunk.

See the attached screenshot.  Why am I not seeing the captcha offered by
Emacswiki?

Please consider this as an umbrella bug.  Eww should do all that is
necessary to view, edit and post to (atleast) Emacswiki.

Bonus points if the Textarea could be edited in the major-mode specific
to markup used by the Wiki engine - Creole, Usemod, Oddmuse, Org,
Markdown whatever.

eww doesn't support iframes, and the captcha is an iframe.

eww could add support for iframes, but it wouldn't really help much
here, because I think recaptcha relies on JavaScript to communicate the
results of the captcha to the originating page.  Doesn't it?  Or does it
work without JS, too?

That might be nice.

I think it should.  Using Eww to edit Emacswiki will be quite handy
indeed.  More importantly, there will be opportunities for improving eww
in (more) useful ways.

According to Emacswiki, "I am human" even if I turn off Javascript.  How
noble?

The workflow is that I get a "response" which I have to manually
copy-paste to another textbox.

Don't forget the scroll bars.

Adding iframe support shouldn't be that difficult, but shr would have to
fetch the iframe src synchronously before rendering the rest.  And
rendering would have to take place in an aux buffer (like table
rendering).  And images...  er...  Ok, it'll take more than ten minutes
to implement.  :-)

Huh.

That's probably not going to happen.
