I can confirm that the deprecation notices have now gone

Is it intentional that the joomla.asset.json files no longer have a version hash?

Commented on the code where there is an error in your math

The hash is not generated automatically per npm ci, you need to run specifically npm run versioning. (the reason is because for development having to invalidate this hash every time you apply some changes in any of the css/js would be an extra step which will be a way slower workflow)
