Well, I can't say I'm that keen on using them, since I prefer to  
abstract my symbols away with meanings. But I wouldn't necessarily  
want to assume that people don't want active plane 1 chars. Perhaps  
an alternative would be to provide support in the same way as LaTeX  
supports UTF8: make the initial char in the surrogate pair active and  
scan ahead...but that's not exactly ideal, especially as XeTeX input  
can be UTF-8 or UTF-16. (Or is it not possible at all?)

No matter what we do, we'll get into the same mess if UTF-64 ever  
comes along :)
