Can you elaborate? I'm not sure I understand what you mean by "now". What I'm asking is whether or not the Play Integrity API supports remote attestation on its own today (ie, before any of the webview changes ship). Or I guess, more specifically, is there a challenge-response API currently for the Play Integrity API that a remote server could use? If yes, then sure, I buy that this is not really adding anything new. If no, then adding a webview API does seem to me like a meaningful expansion of Android's DRM capabilities.
