As you said below...

   “I'm especially interested in what use cases I may have missed
    (please don't say "I think this should be allowed" without giving
    a real-world example), and whether anyone thinks any of the cases
    I think should be allowed should not.”

however, you did not provide a use case.  What is the use case for this? 
  I can't think of any reason to allow tables to be nested inside <p>?

You missed <p><blockquote/></p>.  Do I really have to give a real world 
example for this?  Well, ok...

<p>As you said below:

:-)

<blockcode> should probably be allowed too, though it doesn't seem to be 
included in web apps.  Oh well, that's probably a discussion for another 
thread anyway, if it hasn't already been discussed (I'll search the 
archives later).

It's a shame no browser actually reads the DTD, this wouldn't be a 
problem if they did :-(.  This is one reason why HTML should be a true 
SGML application, and why browsers should have been built to conform.
