The only data I have is 
<>, which is too 
limited in scope to see if there are cases where the difference matters 
in practice.

Looking at that data anyway, there were multiple Content-Type headers on 
about 0.04% of those pages (or 0.02% of the hostnames). (For comparison, 
that's about the same number that use <del> or <var>, and about half the 
number that use "Content-Encoding: deflate"). All of them appear to work 
correctly in browsers regardless of the Content-Type processing, since a 
browser that chooses the "text/html" instead of "text/html; charset=..." 
will fall back on some other method to find the right charset.
