Would this be easy for authors to handle? I don't think so.

If a figure body element is sometimes needed and sometimes not, 
then that would be not be easy for authors either.

Fine, but the problem is the issue of having different content 
models for the same element. Well, technically we have this 
problem already - dt has different content models when inside 
<figure> and when inside <dl>. I think one risks that authors 
would start to add flow content into h1-h6 also /outside/ the 
figure caption context.
