I would like to have the gradle kotlin dsl used instead of the groovy one. It won't go away I suppose but the default is now the kotlin variant for a few years or so.

I suppose the Gradle Groovy/Kotlin one can be available as options for people to select. Groovy is still pretty much the defacto goto anyway.

I would also like to invert the 'ApplicationType' and 'EntityType' Inheritance hierarchy within the generator, so that for example ClientGenerator 'Application' Object won't be able to access 'xChangelog', 'serviceClass', 'databaseType', etc. properties anymore. V9 is the right occasion for this kind of change.

Since Spring Boot 3.5 has been merged, what else is needed for v9?
