What sort of circumstances are you running into this? (Just out of  
curiousity.)

In general I guess I'm not opposed to adding *anything* to the expl3  
code while we're playing around with it. But I suppose every time that  
we write a new module we'll come across the same situation, and it's  
always harder to remove functions than to add them.

Having said that, I'd say just go for it :)
