With the upcoming release of Rails 8, we might want to consider re-generating the Engine to extract the dummy app. This way, our tests are running against a Rails 8 dummy app, and might catch regressions.

Additionally, I think we need to account for the following:

• Should we continue to use Sidekiq as our preferred queuing backend? #1210
• How do we want to handle code auditing now that Rails ships with a solution? #1215
• How do we want to handle CI now that Rails ships with an option? #1216
• New Rails 8 applications generate duplicate CI files #1243
