It strikes me that, if people want web developers to load less stuff, there have to be ways to reduce redundancy. It might also make privacy easier. For example, some sort of self hosted standard based framework for tracking common things like scrolling or ad clicks or page visits that supports multiple consumers, both internal to the site publishers for detailed analytics and logging and ad view tracking, and less granular access for external companies that can add value can get information from. Your user's data stays on your self hosted user data server, and analytics can make server to server requests for aggregate data with GraphQL or a standardized api at least, improving user privacy. If you really needed additional functionality, there could be standardized add-on modules, or updates to the spec.
