I understand if you don't want to reveal your organization affiliations, but if this was widespread, it should have been discussed somewhere with more specifics. Can you link to a discussion anywhere with more specific examples?

We had a bunch of RapidSSL certs in-use internally, and were rather pokey in replacing them since they were less-critical internal certs. Everything with the deprecation warnings were exactly as expected and announced.

I follow Mozilla's dev Security list and the CAB Forum mailing lists fairly regularly, can't find any discussions about Google deviating from their announced plan.
