Hi Matthias,
Indeed we have implemented this in screen server aggregates for mobile and reactive web apps. From our research, this is where pagination is more often needed. We might implement this in other places in the future (server aggregates that are not screen aggregates, local aggregates, traditional web..., feel free to open other ideas if you feel you need those). Read more about the new reactive web apps here.
Thanks for your idea,
Tiago Simões
