This was discussed under the subject “Abolishing DMARC policy
quarantine” in June 2019.  There was no consensus.  SMTP offers this
distinciton and this is mirrored in DMARC.  In particular, senders are
free to publish p=quarantine and receipients are free to interpret it
as p=reject.  Senders can publish p=reject and receivers are free to
interpret it as p=quarantine.

Moreover, some destination addresses do not have the concepts of a
quarantine.  E.g an address that accepts commands for mailing lists
managements.  Such addresses can either accept or reject the message -
there is no quarantine, so interpreting published p=quarantine as
p=reject is feasible.

Recalling the discussion from June 2019 I do not count on any different
consensus, if it the discussion happens here again now.
