Reduce footprint of production jar

grails create-app website results in a website.jar that is 146M

The premise of Micronaut is to not have a monolith app and by forcing it into Grails makes Grails more monolithic adding 13+ more dependencies (plus transitives) to a Grails application

Given the overwhelming lack of support for keeping Micronaut part of Grails, it should be removed or made optional.

Furthermore, creating a Spring Boot app requires a couple of dependencies in build.gradle to get up and going. Why does the most basic grails-app start with 36?

We also need to explore dependency reduction. If a dependency is transitive on another dependency, why is it in build.gradle? It is going to be resolved either way.
