I'd bet it goes down to 0 for 99%+ websites. A few big websites might keep it, but anything that inhibits the site from generating (meaningful) data, like users posting, sharing product feedback, describing fun things to do, showing pictures of an area, etc. will be reduced. What I am betting on is most sites opting for monetizing as data generation, rather than ad serving.

> Splitting

This is one of the things I wished for in the Beam APIs, and I'm glad they included it in the doc. Some (single) elements are bigger than a single function, and can't be processed one at a time. For example. a very large CSV file. They added support for it later (as Splittable DoFn's) but each implementation had varying support for it.
