Re: On the possibility of guidance code points for the PrivateUse Area

Doug Ewell quoted:

The original intent was that if you think you're writing "platform"  
software, you could consider starting at the top of the "Corporate Use  
subarea"; and if you think you're an "end user" you could consider starting  
at the bottom of the "End User subarea".  This would give a way for  
platforms to sort of avoid colliding with real end-user codepoints.

But of course, as Michael points out:
