We have done this with <a>, and the problems it introduces are 
substantial. I'm very reluctant to extend this to more elements.

Yes, I think so. You can special-case a few elements in an editor's UI, 
for example, without extending the complexity to the entire app.

Just don't use <small> at all, and just make the font size smaller in CSS.

That page is a great example of where _not_ to use <small> -- the text on 
there is the main content of the page, it's not a throw-away side comment.

I've added text to this effect.

The issues are things like:

 * It makes it possible to have phrasing-level elements span paragraphs:

     Fred stood up. <i> How are you?
     <p> Are you ok? </i> He sat down again.

 * It makes it very difficult to have intuitive UI in WYSIWYG editors.

 * It leads to confusing parsing behaviour, e.g. there are nested 
   paragraphs here, which is not allowed, and is highly unobvious:

     <p> This is uncontroversial text.
     <ins> <p> This is new text. </ins>
     <del> <p> This is deleted text. </del>

Right.

I agree that this is more borderline. However, you've given this its own 
section, so I wouldn't bother with <small> at all.

I've tried rewording it.

If <small> was a block-level element in HTML4, then I think we'd just make 
it a flow-level element here and give up on inline throw-away comments. 
But as it is, it's the other way around. I don't think we want one element 
to do both, though, and I don't think this use case is important enough to 
bother with if we can't just leverage existing elements.
