guess what? 99% of the apps are not github, neither shopify. You add to your pipeline some automation with https://github.com/fastruby/next_rails and you are done. I'm maintaing a rails app from 2006, with more than 1000 LC (excluding the 2k specs and views) and we are running on rails 7.1. We had one critical moment around rails 5.2 , but after that we managed to keep our stack always up to date.
