Hmmmm, I actually think that we *should* provide access to these via a  
well-defined mechanism. That might be an xpackage job, or maybe they'd  
fit into \toks. But I'd hate to have to give them up (the reason  
they're banned in LaTeX is just that they get overwritten, right? At  
least in the case of \everypar).

Except for the other \every's, I'm not aware of anything else missing  
-- but I haven't manually checked through the listings in l3names.  
There are also a bunch of pdfTeX primitives we're not using.

Yeah, I think we need them all.
