However, I haven't found any information about whether or not they actually pulled the trigger on their plans. Moreover, in my own efforts I haven't been able to conclusively decide if public key pinning support has been removed from recent versions of Chrome. This page seems to suggest it was removed in Chrome 72, but the linked discussion on that page differentiates between dynamic pinning (which is intended to be removed immediately) and static pinning (which may continue to be supported for a longer and unspecified period of time). It's not clear to me from the status page which "kind" of pinning was removed.
So do recent versions of Chrome ignore public key pinning headers? Have Firefox or Opera followed suit?
