Author of open-pdf-sign here. AdES alone is difficult to do without proper signatures and user verification. Besides that, if Google would go for advanced electronic signatures, I'd expect it showing up in the EU Trusted List, which it isn't. So unless Google is not utilizing their own Google Trust Services certificate authority, I'd say it's unlikely that they will launch with AdES that are compatible with eIDAS.

Thanks for your answer, I appreciate it.

Although strictly speaking if they would only want to do AdES and not QES, they wouldn't have to be in the EU Trusted List, would they?
