Good idea. I did not consider this before.

However, if you look at the LaTeX source code, you see that the last two 
are not actually frames, i.e. the content is not in a frame environment. 
Separators are general, i.e. they do not say what kind of environment 
they separate. One always needs a frame environment to create a "proper" 
frame.

Actually, in your case, the separator has only the function that they 
begin a new paragraph (rather than a new frame). But this can also be 
achieved by just starting a new line. You can actually remove the last 
two separators and it will look exactly the same. The frames are only 
broken at the paragraph breaks.

Furthermore, even if one needs a separator in certain cases, this 
doesn't mean that the other cases couldn't be better handled without.
