CMP / Funding Choices for AMP

Hi, we are working on converting all our sites to AMP responsive tech, for desktop / mobile users. We are using Adsense and Ad Manager, and we have some issues with the update of the rules regarding consent for advertising. As we still have some desktop sites in standard HTML, our Google Account Manager suggested that we use the Funding Choices CMP script. This solution is great as really simple to implement.

On the other hand, we have been searching for a simple CMP solution for AMP. Right now, there are only some CMP for AMP commercial solutions (expensive). How come Google is working so hard on pushing AMP and does not provide a turnkey solution for AMP CMP based on Funding Choices. When could we expect such AMP CMP solution ? Indeed, we adopted your AMP solution really early (2017) and this situation with CMP is like a brick wall for us.
