Safari will no longer trust certs valid for more than 13 months
There are two mutually exclusive views of the web. As a set of protocols to allow individual humans to share information about things they love and the web as a set of protocols to make a living.There are real reasons for the for-profit web to want to limited cert lifetimes since revocation doesn't really work in practice. In terms of browser dev the two views are mutually exclusive and the one that funds the coders gets it's way. Especially with the W3C marginalized and a mix of corporations and corporate-centric standards groups running things now. Expect to eventually be unable to host a visitable or indexable website without relying on at least one third party service in the near future.
