What are specific "innovative approaches to perfromance" is wiz bringing?

Even though it's claimed that it powers many of Google's websites, most of those websites are very far from being paragons of performance.

It introduced very fine-grained code loading on interaction and something the community refers to as resumability.

Could be interesting/useful, but none of these seem to have any impact on the sites like Youtube which loads tens of megabytes of resources, and every interaction takes a second or so to happen.

Other sites like Photos are fast and performant, but I wonder if it's due to whatever perceived advantages of Wiz or due to the team actually caring: https://medium.com/google-design/google-photos-45b714dfbed1

Performance always needs to be a priority for a team to hit satisfying metrics.

Wiz is designed to make it harder to get bad metrics if performance is not your top goal.
