One way of looking at is that these /are/ the PM's own variables, simply 
exposed read-only to make life simpler.  There's nothing you can't do by 
setting your own variables initially equal to the read-only vars and 
modifying them as you wish, that you could do if the PM exported them 
writable but ignored any rewritten values itself.  Either a read-only 
variable works fine, or a rewritable value then ignored by the PM 
wouldn't work either.
