(This is not a problem or bug description, just a reflection on and curiosity about the various ways one can configure the stack.)
The Things Stack can be configured using command-line flags, environment variables, or configuration files.
While i can see that some methods might be better suited for experimental runtime changes (command-line flags), others for permanent settings (environment, files),
do you see a general preference for one method over the others, or is it just a matter of taste? Is there a best practice?
