Paginated API list views are such a common pattern throughout the app, that we could benefit from having a shared abstraction between e.g. feature flags, insights, annotations, etc. This could take the shape of a paginatedLoader() kea logic builder, which would automatically keep track of the pagination counts, next URLs, etc.
