Windowed grids probably aren't very common because most services with tons of data just have DynamoDB backed table views where pages are lazily fetched rather than sourcing data all upfront. A tree UI would make sense for the S3 console, but they currently just nav to a new page for each subtree path. I just remembered that I actually built a windowed grid implementation on top of the provided table component as well at one point. Can't really point to it, since it's on a console page only visible to a few enterprise customers. It's worth pointing out that patterns in the AWS-wide design system take some time to get included. If a single team has a use-case for something, they'll often make a feature request and build their own bespoke component to use before things get standardized. Back in the day, neither the table nor datepicker components were available, so I had to roll my own, for example.
