Yes.

Because this is the only way that application developers will learn to
handle it.

(When I first learned that T-Online was forcing this on their customers,
I was quite upset.  After thinking about it for a few weeks, I came to the
conclusion that it's the inevitable and correct approach.  If you make
the homenet renumber only "every few months", like "when the router is
offline for longer than <x> hours", people and application developers
will start assuming that IPv6 addresses are something static - and then,
when that renumbering happens, you'll get uproar and support calls.  
Force a prefix change on homenets once a week, and developers will learn 
how to cope with it, without breaking every time, requiring application / 
appliance restarts, etc)
