Thanks for your clarifications, Alex and Frank. Thanks also to Leena
for swiftly updating the documentation:
https://codereview.qt-project.org/#/c/231875/

Just to check my understanding: Is "Qt for Automation" essentially a
package/bundle that contains the following modules and their
dependencies?

* Qt Virtual Keyboard
* Qt Quick Controls 2
* Qt Quick Compiler
* Qt WebEngine
* Qt Serial Bus
* Qt Quick WebGL Streaming plugin
* Qt MQTT
* Qt KNX
* Qt OPC UA

Is there any special tooling (other than what's already available with
the pre-built Qt Creator)?
