To respond explicitly to this point -- yes, page-level fallback is needed.

It isn't the best way to do accessibility, but it is better than nothing, and
there are times when the original media can't be edited.  This might be
because it is on another server, or because of copyright constraints, or
just because the author doesn't know how; the point is that the case will
arise, and better non-HTML tools will never make it go away entirely.

I personally think a final <source> element is a fine location; the final
source element does not need to specify media or type, but I suppose
type of text/html is fine for use as a fallback.
