Yes, except that <blockquote> works, and <blockcode> doesn't. Also, 
<blockquote>'s content model is further block-level elements, whereas <q>s 
isn't; whereas <pre>'s content model is inline content, the same as 
<code>.

So <pre><code> is actually closer to <p><q> than <div><q>, from a syntax 
point of view.

Could you explain? I don't see any nested paragraphs there, nor in the 
definition in the spec (which is more important I guess).

I agree.

Fair enough.
