Further, considering the very real and distinct performance characteristics of mobile (radio warmups, RTTs, initcwnds), the idea of fetching OCSP, or, worse, CRLs - especially when some CAs have CRLs that are quite large (20+ MB) - in order to assure the EV display is... non-ideal. So again, the EV indicator on mobile is not as strong or as present as it may be on desktop platforms. In that case, what does this statement mean? Chrome for mobile platforms will cease to show EV indicators for certificates that are not CT qualified according to the criteria below. It means that for any CAs that hope to be recognized as EV on Chrome for mobile platforms (which include iOS), implementing CT by the dates outlined is seen as a requirement for such treatment. We wanted to specifically call attention to this - the whitelist is seen as a temporary measure for Desktop, but given the unique characteristics of mobile platforms, we're pursuing this requirement at a more aggressive pace. While Chrome for Android - and the Chrome-based WebView, as the WebView preceding it - do not provide special treatment for EV, any future plans for EV indications on these platforms have incorporated the above requirements and dates. In that case, my original objection stands - this policy retroactively downgrades existing EV certificates if and when a mobile platform chooses to implement an EV indicator. There are certainly times when it's necessary to apply a new policy to existing certificates to protect relying parties, but IMO this isn't one of them.
