Have we not learnt from v4?

If there are to be filters then they should be defined once and never
changed as people will fail to update

If a different allocation requirement arises then start a new prefix
(v6 is big enough to handle this) and define its filter once. Do not
allocate it from an existing range and expect people to adjust their
filters.
