Sure, but two motivations:

1) In fine Arabic typesetting this can occur literally dozens of times a  
page, so I need something visible/convenient analogous to tilda/~ (which  
-- I am ashamed to say -- I still use in mkiv)

2) I can't currently "see" "202F in my editor (notepad++) and the current  
syntax-highlighting features don't display it automatically.

(Eventually I have to port the ConTeXt support package for Npp to a  
lexer/plugin where I can define these things explicitly, but first I need  
someone who knows that lexer stuff to help...)

Best wishes
