Makes sure to have `routesGenerator := InjectedRoutesGenerator` in your Play/SBT build

I'm wondering whether it's not trigger by the `ConsumerStage`, as I cannot reproduce it in the same env directly using the Kafka client.

Then it's important to clearly state that point in the migration guide. I haven't personally seen anything about (neither in the source quote).

The tutorial doesn't indicate that unlike Scala 2 macro there is no need to do anything special to have fresh term name, so that's different issue.

It was extracted, as useful, and no longer works
