I did not claim it was implausible.  I claimed it was hypothetical 
because it was presented without any evidence to back it up.  There have 
since been some examples presented, which is good, but still no 
explanation of what problems are caused.

But, here's some evidence to support the definition of class="copyright" 
in the spec.  The following sites all use the value in a relatively 
compatible way.  Although some use it on elements other than those 
allowed by the spec, it's the value that's important.  However, I agree 
that's a bug in the spec.


These used id="copyright", but it's the value that's important, not the 
specific attribute.


These used similar values.  While they're not exactly the same, they're 
close enough to be considered in support of "copyright".

http://ninemsn.com.au/ (used class="copyrightline" which is similar)
http://youtube.com/ (used id=="footCopyright")

It is clearly stated in the introduction that the study used "a sample 
of slightly over a billion documents".  Hixie has also done subsequent, 
though unpublished, studies with much greater sample sizes.
