This would make the behavior very ambiguous if you were using both the
blocking command and privacy lists. I think that if you're using both,
this bit should remain (of course, you could just be using one or the
other, in which case it doesn't matter).
What's really being said here is "ensure that there's a two way mapping
between the default privacy list and the blocklist"... actual backend
storage method is irrelavant (I could store them separately, and just
make sure they both get updated; not sure what the point would be to
that of course, I'm just pointing out the purpose of the statement).

In line with the above: "Where an implementation uses both Privacy Lists
and Block Lists with a common backend"...
That's what I've been rapidly moving towards myself. In the discussion
Holger and I have been having out of band, we were tossing around
similar ideas, though more implementation specific.
In summary (if I'm understanding correctly):
If you're using both privacy lists and blocklists, ensure that there is
a direct two way mapping between the two (probably by just using the
same backend datastore), but only if the request follows the exact
semantics of the blocking command (eg. is a block command, or is a
privacy list that matches the block command exactly).
