I'm saying it still represents small text, and that there are legitimate 
use cases for it.  Whether or not those use cases are largely compatible 
with existing real world usage is certainly questionable and needs 
researching, but it's definition in HTML5 is compatible with it's 
definition in HTML4.

<big> does not have any known legitimate use cases.  The issue is not as 
black and white as simply being a presentational vs. a 
non-presentational element.

Do you have any evidence/references to support that claim?

Copyright statements and other legal notices that typically occur at the 
end of web pages (the use cases for which this is intended) are quite 
often presented in a smaller font.

I've addressed the issue of b and i before.

The definition of strong and em has always been rather ambiguous in 
previous versions of HTML.  HTML5 refines their definitions in a useful 
and compatible way.

The definition of HR in HTML 2.0 was:

   The <HR> element is a divider between sections of text; typically a
   full width horizontal rule or equivalent graphic.

In HTML 3.2, that became:

   Horizontal rules may be used to indicate a change in topic. In a
   speech based user agent, the rule could be rendered as a pause.

In HTML 4.01, that became:

   The HR element causes a horizontal rule to be rendered by visual user

The HTML4 definition is entirely presentational and not at all useful. 
HTML5 defines it in a way that is more compatible with its semantics in 
HTML 2.0 and 3.2.

   The hr element represents a paragraph-level thematic break, e.g. a
   scene change in a story, or a transition to another topic within a
   section of a reference book.

That also illustrates that changes in definition have occurred in the 
past and that such changes are not as serious as you claim.

You're argument seems to be based on the fallacy that minor changes to 
semantics could seriously alter the processing, but that is not true 
because the processing requirements will also be defined in a way that 
is compatible with legacy content and UAs.

Ideally, the spec would give guidance for non-visual UAs, based on how 
such UAs handle it today.  HTML5 will not intentionally define 
processing requirements that are significantly incompatible with legacy

It doesn't displace the problem at all.  The user will know what they 
have used the elements for, and so the problem will have always been 
with them, not the editor.

If you only used <small> for presentational purposes in you're document, 
then there is little problem in replacing them with CSS.  If you know 
you only used them for semantic purposes, then don't let you're editor 
change them.  If you used it for both semantic and presentational 
purposes, that's your problem.  It is no different, for example, from 
using <em> for emphasis in some cases, and general purpose italics in
