The concern is hypothetical, since <object> is so rarely used.
Nonetheless, you're acting as though <object> were a replacement for
<img>. (It is in XHTML 2, but who cares about that?) <object> is meant to
replace the nonstandard <embed>. The whole idea is a failure, but since
we're trying to understand how it's supposed to work, then for
accessibility we're talking about:
<object>
{multimedia with captions and/or descriptions}
</object>
That's it, really. Of course you could imagine nesting other <object>
elements with e.g. still pictures with text equivalents, but that's not
the purpose of <object>. Someone from Australia will write in to emphasize
hypothetical counterexamples, but they can be ignored.
In any event, a conforming screen reader would recognize that it cannot
render a still image and would instead read a nested text equivalent. This
behaviour is in no way different from the way they currently handle <img>.
That same screen reader would give direct access to the multimedia;
user-agent issues are entrained in that process, but they're not our
responsibility.
There simply isn't a problem. Remember, the screen reader is also a user
agent. Don't be misled by what a browser does without a screen reader..
