In practice the Web PKI is overseen by the general public, via Mozilla's m.d.s.policy. It makes no sense for the proprietary vendors, including Google, to insist on doing something themselves badly when Mozilla is the obvious host for this work.
The older vendors are even less able to be properly open with their customers (let alone the general public) than Google. At Apple it's probably a firing offence to even confirm obvious decisions - it seemingly took months to get Apple's chosen representative to confirm that Apple's new 398 day rule was an issuance requirement, rather than just something where Apple wouldn't trust longer lived certs in Safari.

none of what you list are good excuses for anything. I fail to see the point. Is it that marketing trumps technical know how and it should be ok?
