I won't say that it never changes, but generally it has not.

Prefix is 2607:F780:1::/48 assign /60 prefix
1 entries in use, 4095 available, 0 rejected
0 entries cached, 1000 maximum

User                Prefix                                      Interface
0001000110D1D32C001 2607:F780:1::/60                            AT5/0.14250

I presume it will stay the same as long as cache works.
