I wouldn't say it's as clear cut as that, just as similar statements
like "a site must work even when JavaScript is disabled" aren't exactly
true either. Neither of these statements can be found anywhere in the
letter (nor the spirit, I'd argue) of WCAG 2.0.

The "other things" mentioned in the original post may also well be
dialog boxes, alerts, error messages etc which are intentionally styled
with display:none to not be visible / absent from the DOM that's exposed
to AT, and will only be made visible when appropriate. So again, it's
not a clear-cut situation - without seeing the actual specific case,
it's not possible to make generalised statements about things being
incorrect.
