Why is this needed?

Why can't IntelliJ just create the project? Isn't that what IDEs are made for?

This just makes it seem very hacky and looks like a workaround.
Please just let us create the projects from IntelliJ.
I love the Kotlin language but the infrastructure around creating, managing and maintaining projects really makes it frustrating and nowadays the huge variation in project types and what is supported is really confusing.

The issue names no files, tests, or entry points; begin by defining which project types IntelliJ should create and how they should be managed. Compare that expected workflow with the current project-creation experience, and consider the work done only when supported projects can be created from IntelliJ without the described workaround.
