% sbt -version
sbt version in this project: 1.3.5
If I ask sbt to create the template, it will fail to do so:

However, if I specify sbt version as in build.properties of this template

Akka mentions sbt requirement in it's instruction(https://github.com/akka/akka-quickstart-scala.g8) sbt -Dsbt.version=1.3.6 new akka/akka-quickstart-scala.g8. I think ce3.g8 should do the same.
After #3, if the actions added there are passing, any commit from @scala-steward should be merged automatically.
Some stub of testing using the testkit would be really nice. Maybe with weaver-test too...
To be decided: which framework? All of them? Conditional?
Candidates:
ce3.g8 isn't a sane default for generated projects.
Whenever a Scala 3 mode will be available for g8 it would be awesome to do not include better-monadic-for as a plugin.
What about adding better-monadic-for? Documentation highly suggest it for scala 2. If the scala version gets parametrized probably it can be disabled for scala 3 builds.
