Or it could be broken in the same way. 

These are quality of implementation issues. Browsers can fix them without spec change. 

AFAIK there is nothing in the spec that requires browsers to download all resources from <object> — they can skip unsupported types and stop downloads after the first object that works.

Browsers are also free to support right click on the object.

I support addition of <picture>, but weak <object> implementation doesn't seem like a strong argument for it. 

If browsers happen to implement <picture> poorly as well I won't advocate creation of a  <picture2> element :)
