Feature request: Floating/sticky sidebar

Hi, while checking out the recently added starter site “Service 2.0” I noticed that the following page includes a floating/sticky sidebar element on the right (containing “Categories” and “Latest articles”): https://sites.generatepress.com/service-2/blog/

Would it be possible to somehow implement the sticky property for sidebars for the GP theme generally to let users select it for sidebars? I believe many customers would find it very useful as it’s a common demand nowadays and therefore eliminating somewhat annoying implementations still required since WP still doesn’t support such a feature.
