I don't think it does/did. My reasoning was that either:

 a) Packages "may" be added → you need to adjust your config as this
    is something that can happen in practice, or;

 b) Packages "may not" be added as a general rule and this was an
    accident mistake or oversight → you need to adjust your config
    anyway as its clearly something that can happen in the real
    world regardless of learning what the policy is.
    (This so-called "policy" could change in the future anyway for
    special problems we have no possible idea today about the
    solutions are. See, for example, new packages introduced as part
    of DSA-1571-1, SPECTURE/meltdown detection, or whatever...)

As it happens "a)" is the reality — and it's naturally always good to
get clarification — but note that in both cases you need to upjust
your unattended-upgrades configuration, hence my use of "academic".

Best wishes,
