Discord is evaluating this functionality:

“We are presently conducting trials in specific areas to restrict access to certain locations or user configurations,” a representative from Discord mentioned in a statement. “The data shared to facilitate the age verification process is solely utilized for that singular verification step and is not retained by Discord or our partner. For Face Scan, our partner’s solution functions on-device, signifying that no biometric data is gathered when you perform the face scan. Regarding ID verification, the scan of your identification is erased once verification is completed.”

I eagerly anticipate all the footage of individuals circumventing this system with various alterations in appearance.
