Views summarize future proof alternative?

This is the message on the /admin/reports/updates page:

Views Summarize 1.1.x-dev (2021-Feb-20)
Project not supported: This project is no longer supported, and is no longer available for download. Uninstalling everything included by this project is strongly recommended!
Includes: Views summarize

And that seems different from the module's homepage. Further I am using it on Drupal 11.2 with no problems at all.

Good to know this one is working. I recently did a deep dive on these kinds of views aggregation and calculation features.

This looks similar to Views Aggregator Plus, but that one can only do single row aggregation results.

One pattern I am seeing is that the data is too tightly coupled with the display. I haven't looked at this module's code yet, but for example, Views Aggregator Plus handles the calculations in the display plugin. I would like to instead have views plugins that do the calculations and then provide variables that could be used in any display template. This is a tricky problem from a UX/DX perspective since views is quite complex under the hood. I also pondered what it would be like to integrate views with a library that can handle this on the front end, but it seems like a full stack solution is the best way to go, especially when handling pagers with dynamic sorts/filters.

Here's a collection of modules, issues, and notes related to the effort: https://contrib.drupalarchitect.info/task/advanced-views-calculations

I was attempting to build a financial/accounting dashboard, where these kinds of summaries would be nice.
