You are asserting that gmail will eventually do what Yahoo has done. I can't speak for my employer, but I suspect there will be a lot of people (both inside and outside of the company) lobbying to make sure gmail doesn't do the same insane thing that Yahoo has done. I have quite a bit of faith that senior folks like Vint Cerf will take a bit more of a nuanced view than some of the DMARC cheerleaders have done, and his voice does carry a fair amount of weight. Cheers, - Ted P.S. One of the reasons why I think mailing list software should pick mechanisms that inflict pain on yahoo.com customers, and hopefully get them to switch, is that hopefully other e-mail providers will consider the costs of using DMARC p=reject for domains where users might need to send mail to mailing list, and choose differently from Yahoo.
