Yes, but a policy _can_ be put forward in DNS without DMARC; either of
these sets a policy:
_adsp._domainkey.example.org. 86400 IN TXT "dkim=all"
_asp._domainkey.example.org. 86400 IN TXT "dkim=all"
_domainkey.example.org. 86400 IN TXT "o=-\;"
DMARC is better but it is not the only existing solution.
