If there's a need for an explanation as to the "why", here's a generic one:
"Unicode is changing. Many of the policies exist to allow current
software to be forwardly compatible - in other words, to survive after
newer software has been written writing date base on an updated version
of Unicode. Other policies exist to help with the reverse.
The effects of any of these policies may appear arbitrary if viewed from
the perspective of a single point in time and a particular application
of the standard. They may even seem to make some things more difficult
to achieve. Overall, though, their effect is to simplify the interaction
among cooperating software items that were written at different times,
with different Unicode versions in mind. That makes them indispensable."
I think some high-level discussion like that might be better than merely
stating "this is how it is".
