This is going to cause difficulties in deployment for a lot of companies and 
domains. Experience tells us that p=quarantine pct=0 detects forwarders and 
other types systems that modify and break DMARC authentication. These systems 
are undetectable when p=none is in place. 

I understand and support removing PCT 1 - 99, but think that removing pct=0 
will make it even more difficult for companies to deploy DMARC.
