- iframe fallback - is it needed in practice?

In principle, the iframe element is defined to allow graceful fallback: just
put the fallback content inside the iframe element. But is this relevant in
practice? That is, are there user agents (in "real-life use") these days
that do not implement iframe?
Lynx renders iframe content but it also displays
followed by the src attribute's value turned to a link, so this normally
makes the fallback redundant.
Opera has a setting for disabling iframe support, implying that fallback
content will be rendered instead. Does anyone use this? It might be useful
to authors for testing - if it were relevant to test that pages work on
iframe-disabled browsers, but is it?
Any other browsers we should know about, in this respect?

The Firefox NoScript plugin can be configured to block iframes, which can
be used to protect oneself against clickjacking:
